better then any image you could just download and print
After becoming frustrated with the images of periodic tables available to download I decided to buy a few periodic tables. This one is labeled basic but it more then that. It is one laminate page (no unfolding) and includes on the table for each element; atomic number, atomic weight, atomic symbol, if it is radioactive or not, oxidation state, 1st Ionization Potential, the electron (spdf) configuration, and the written out name on both the front and the back. The elements are color coded to indicate whether it's a solid, liquid, gas or artificially prepared.It also includes as extra the major isotopes w % of occurrence, a few metric conversions and units, a side by side graph of Fahrenheit Celsius and Kelvin, a few prefix names, and some laws constants and equations that you are supposed to remember.

My only gripe is that it is smaller print then the Advanced Periodic Table from Quickstudy. I am young and my eyes are pretty good so it is ok for me but I know that anyone with some vision problems might have a harder time reading it. But in exchange for smaller print I also get one page no foldout which is more portable and convenient. I can pull it out, place it in front of my notebook while I am working and just look up to find what I am looking for rather then opening something. To be fair I have both and use both. Additionally, for homework use I bought the big blue poster and framed it and use that almost exclusively at home because large print really is just easier to read. ... Read more

a very good product
I like this a lot.It's on cardstock and it's laminated, and it really does help to have this open in front of you as you're working.It makes doing problems and calculations so much easier.In class people always wanted to borrow it.Bear in mind that professors often will NOT allow this to be used during exams--it really is a mini-textbook with all the information on the back.Very durable.

Excellent chart
Just what I needed to have handy in my studies. The paper ones were getting worn out.

A rich, durable, and handy reference of the Periodic Table and the properties of the elements
This is a terrific version of the periodic table for the serious science student.It has the atomic number, atomic weight, electronegativity, atomic radii and ionic radii, elctron affinity, and 1st ionization potential.It even defines what these terms mean, but if you can use the information, you already know.This chart covers the front two pages of this laminated chart (quite durable).

The back of the chart has eight versions of the table that cover enthalpy of atomization, natural forms (solid, liquid, gas), molar volume, density, enthalpy of vaporization, boiling point, enthalpy of fusion, melting point, specific heat capacity, and thermal conductivity.The other back page provides some chemical properties of the elements and common uses.

All in all, a very interesting and useful chart.It might be overwhelming if all you are looking for is the name, symbol, and atomic number, though.

As I noted, it is laminated for durability and it is also three-hole-punched so it will fit easily in a student's notebook.

A Lot Of Information On Four (4) Pages.
The most up to date I have ... but still behind the times.Had names for elements up to 109.I know that element 110 and 111 have been named but the chart have them unnamed.Element 118 is on the chart even though the discoverers have removed their claim of discovery due to errors in their detection equipment.
The chart has the usual information on the elements as most charts will have ... Name, Atomic Symbol, Atomic Number, Atomic Weight, Density, Electron Configuration, Oxidation States, Melting Point, Boiling Point and more on all of the elements up to 103.
All this info folds up and will fit in a standard 3 ring note book. ... Read more

Product Description
The story of the enigmatic man who organized chemistry into the periodic table--and of how he tried to organize Imperial Russia.

Dmitrii Mendeleev: It's a name we recognize, but only as the disheveled scientist pictured in our high school chemistry textbook, the creator of the periodic table of elements. Until now little has been known about the man, but A Well-Ordered Thing draws a portrait of this chemist in three full dimensions.

Historian Michael Gordin also details Mendeleev's complex relationship with the Russian Empire that was his home. From his attack on Spiritualism to his humiliation at the hands of the Petersburg Academy of Sciences, from his near-mythical hot-air balloon trip to his failed voyage to the Arctic, this is the story of an extraordinary man deeply invested in the good of his country. And the ideals that shaped his work in politics and culture were the same ones that led a young chemistry professor to start putting elements in order.

Mendeleev was a loyal subject of the Tsar, but he was also a maverick who thought that only an outsider could perfect a modern Russia. A Well-Ordered Thing is a fascinating glimpse into the world of Imperial Russia--and into the life of one of its most notorious minds.Amazon.com Review
An academic biography, Michael D. Gordin's A Well-Ordered Thing tells Dmitri Mendeleev's story in dense prose, detailed with Russian history and molecular chemistry. Mendeleev will forever be remembered as the inventor of the periodic table of the elements, which sorts hydrogen, helium, lithium, and so on, according to their weights and properties. Readers unfamiliar with either the periodic table or the politics of Imperial Russia will have a tough go of it. Nevertheless, Gordin's treatment reveals surprising facts about the enigmatic Mendeleev and his social context.

The periodic system was developed in Russia by an individual who was ... trying to bring order to a Russian society that was apparently disintegrating.... In order to understand the building of this part of modern chemistry, one must come to terms with the attempts to create a modern Russia.

Deep, thought-provoking book about Russia and this great genius...
It's difficult to 'grade' a book that refused to stay on what the intended topic (as presented to the reader). When I ordered the book, I thought the picture of Mendeleev was a rather haunting one, that looked like so many of the great minds like Da Vinci, Michaelangelo, and other minds from the slightly earlier time of the Enlightenment. This was a man who started his life in the time of horse and carriage, of gas lights, of sloppy science in Russia, and ended in the next century when his country was beset by revolution...one of the very things this authoritarian abhored.

Grodin wrote a fascinating and difficult book to read. He starts out with the information Mendeleev is most known for...the periodic table. Yet, a lot of the information here in this part of the book is almost 'circumstantial' and did not add much more than what I already knew.

However, the following chapters demonstrated that Mendeleev applied his organizational skills to many other areas in both science and social life in Russia, and though it was not expected by the reader, the information is emmensely interesting. Russia was the backwards part of Europe, just as the South was the backwards part of the United States. Mendeleev worked to bring that same organization used in chemistry to make sense of the elements to such diverse areas of need in Russia such as her economic life and the deeply engrained superstition that became so fashionable in both Russia and the U.S. and Britain at the turn of the century. All thesee countries dabbled in seances or otherworldly things in the guest to understand one of the least knowable things: death and the afterlife. Mendeleev had not patience with this kind of chicanery and strenously tried to disprove it's existence with science.

Grodin's choice for a title could only be determined through reading the book as a whole. The greatest achievement of Mendeleev shadowed his much larger life as a diplomat, as a world-class scientist trying to bring his country into a new century. Not an easy book to read, but definitely a worth-while one!

Chemistry

First part of book great, but I could not finish.
Chapters 1-3 of this book were exactly what I expected with the history of Mendeleev and the periodic table.However, the author mentions at the end of chapter three that Medeleev did not work on the periodic table from that point on to the end of his life.

My primary reason for reading the book was to learn about the history of the periodic table. I stopped reading in the middle of chapter four when Mendeleev was pursuing other interests.

The first three chapters are excellent if you are interested in the periodic table, and the rest of the book may be of great interest to a reader interested in other facets of Mendeleev's life.I encourage anyone to buy this book, but I don't believe the last half of the book will be of interest to me.

Fascinating True Story of a Russian, Scientist, and Genius
+++++

When I studied chemistry in high school, I was taught that Mendeleev (pronounced Men-de-LAY-ev) was, due to his "Periodic Law," the inspiration behind the periodic table of chemical elements, perhaps "the most widely recognized talisman of modern science."And that was it!Nothing more was said.Thus, I thought that Mendeleev was only of importance due to his association with the periodic table.I thought this until I picked up this book and learned how wrong I was!

This extremely well researched book (that won the Basic Prize in the History of Science) by Assistant Professor of History Michael Gordin is about Dmitrii Mendeleev (1834 to 1907) and the Russian Empire.

This is not your typical (boring) biography that runs from Mendeleev's birth to his death.Gordin explains: "I concentrate on Mendeleev and the Russian Empire from [the] Emancipation [of the Serfs in 1861] to the [Russian] Revolution of 1905, the epoch of Mendeleev's greatest chemical achievements and of Russia's greatest hope for a reformed liberal state.I have selected seven major episodes from Mendeleev's life not because they were...the `most important'...but because each emphasizes a different feature of the cultural life of both Imperial [Russia] and nineteenth-century science."

You'll learn from this book that Mendeleev was more than just a chemist.His other credentials include father, author, economist, bureaucrat & public servant, meteorologist, and aviator to name just a few.Gordin elaborates: "[I]t is hard to conceive that one person occupied all the roles this man played."The author continues: "[H]is life illustrates what it was like to live and work in [Russia]."As a consequence the reader will learn much about Russia in general and about St. Petersburg (the city where Mendeleev worked) in particular during the period 1860 to 1905.

This book contains almost ten black and white illustrations and ten black and white frontispiece images.My favorite illustration is "Short-form periodic system from [an]...1870 article [written by Mendeleev]."A couple of the illustrations are too
dark.

Although not absolutely necessary, I would know some basics of general chemistry and a bit about the history of Russia during the time period concerned in order to fully enjoy this book.The author does do a good job in explaining basic chemical terms.

My only minor quibble with the book is that it gives the impression that Mendeleev was the only one that made a table of the elements.This is not quite true.However, his was the first one that was scientifically useful.Also, it would have been instructive to include in this book a modern periodic table to illustrate the modification that atomic numbers are now used instead of atomic weights (which Mendeleev used) to order the elements.

Finally, I was surprised that there was no mention of the chemical element named after Mendeleev.It's called Mendelevium (symbol Md).

In conclusion, until this book came out, DmitriiMendeleev's life was "shrouded in [a] historical fog."Read this book to learn why "he remains the most recognized Russian scientific name both at home and abroad!!"

(first published 2004; note to the reader; preface; introductory chapter; 7 chapters; concluding chapter; main narrative of 250 pages; acknowledgements; extensive notes; extensive bibliography; index)

An exciting, enlightening survey
When young Dmitrii Mendeleev drafted the Periodic Table of Elements as a guide for his chemistry students, he was already dreaming of building a scientific empire in his home of Russia - with himself at its center. His Periodic Table predicted the existence of three unknown elements and helped foster the entire science of chemistry, so it's sad to learn the name of Dmitrii Mendeleev himself has been relatively lost in relation to his creation. Micahel D. Gordon's A Well-Ordered Thing: Dmitrii Mendeleev And The Shadow Of The Periodic Table resolves this neglect, providing an excellent review of both the Table's importance and Mendeleev's stormy relationship with his Russian background. An exciting, enlightening survey evolves.

Story of a great man - by an ingenious historian
I've heard a part of story of Mendeleev directly from Michael Gordin during the dinners in the Harvard Society of Fellows, and the discussions with Michael were always extremely insightful as well as entertaining.

One of the main reasons is that Michael knows a lot, and he is interested in everything. My feeling is that he knows more about Russian history than those who are specialized in humanities. Think about any two people whom you know and who lived in the 19th century or the early 20th century (two Russian writers, for example), and Michael will be able to tell you what was the relationship between these two people, when they met, and why it was important. What you read in this book about Mendeleev is just a fraction of what Michael could tell you about the 19th century.

Moreover, he also understands the important technical points of chemistry - in fact, not just chemistry: physics, mathematics, and other sciences are his cup of tea, too. Therefore his presentation is not superficial: you will learn the right things about the right ideas and their evolution, about the wrong ideas as well as about the influence of politics and ghosts.

Michael Gordin's Russian is very good and it helped him to understand all the relevant events and links between the contemporaries of Mendeleev as he studied the archives in St Petersburg (and perhaps also Moscow). Incidentally, he also learned Czech - which is my first language - because at some moment he decided that it is helpful to follow some old letters about chemistry.

Anyone who is interested in chemistry, history of science, or Russian history should immediately buy this book because Michael Gordin was the right person to write it, and you will certainly learn a lot about all these issues. Moreover, Mendeleev might be the most famous chemist ever and his life was rich enough to keep you excited as you read through these 300+ pages of a superb text. ... Read more

Thousands of years of discoveries in Chemistry wrapped up in 58 pages
Another delightful little tome by Wooden Books, that takes an immense and complicated subject and condenses it into 58 (really only 29 ,because half are illustrations)pages. It is done in such a way that anyone,regardless of their scientific education,will find it a fascinating journey into what science knows about how our world is made up.It is a great example of demonstrating how simplicity is the measure of genius.It takes terms ,concepts etc., that everyone has heard ,one time or another;as well as scientific terms that most have never heard and explains them in a way that shows how they all combine to make our world what it is.The complexity of our world is simply mindboggling and we can only wonder ,inspite of all the discoveries,how little we really know about everything--or as a matter of fact--about anything.Throughout history,mankind has always had a sense of wonder about the world around him;some actually believedthey knew all the answers,but as the future continues,mankind continues to discover things that have never even been imagined.
Just imagine if ihe wisest men at the time ,say at the beginning of the 1st Century,sat around a table,with this book in their hands,how amazed they would have been to learn what was between its covers. Now,just think how a similar group would think how little we knew,if they were looking at a revised copy in the 30th Century.
Today; we wonder how the ancients built the Pyramids with knowing so little;will they wonder how we explored space ,with our present day knowledge?

How's this for demonstrating a point?

How big would the Earth be if it had no air between its atoms? About as big as a baseball...."Uncle John's 15th AHH- INSPIRING Bathroom Reader"..Page 299

Good, but not useful
The book very briefly lists our current knowledge of the atomic world.

The issue I have is that for those who are even vaguely familiar with the subject already, the book provides no more knowledge.For those who are not familiar, they would albeit get to know about the terms used in Physics, but would gain no appreciation or true understanding of it.(In the sense that you learn that the Earth is round, but appreciating this fact requires understanding how mankind learned that, and what kind of surprise it was for them to learn this.)

Feynman once asked his father why the ball on the top of his toy truck moves backwards (with respect to the truck) if he pushes the truck forward.His father answered that nobody knows!He could have said that it is because of inertia blah blah.But that does not answer the question, it only gives new terminology to ask the same question all over again (what is inertia).

By telling Feynman that the answer is not known, his father developed his curiosity and simultaneously prevented him from developing biases.

This book gives you all the answers without making you appreciate how all that came about.Its doing exactly the opposite of what Feynman's father did to him.

By the way:I have read a few other books from the Wooden Books series.I usually love them.

Totally original
This is a really fun book.It successfully manages to get across the massive amount of weirdness down in the smaller end of things.My sons love it.Some of the pictures are the best I've seen anywhere.A little bit of a pity it didn't go into bond angles and so organic chemistry (lack of space I guess),and, as another reviewer has noted, there are some weak places ...but I just love the feel of the book, the way the subjects have been handled, and, unlike so many 'popular' chemistry books, this one at least has a beautifully designed periodic table at the back!Really highly recommended for kids or for adults who need their science refreshing.

Should have had a chemist review your manuscript.
This is a "cute" book for its' size and illustrations.Not especially informative, but I suppose it wasn't meant to be.
However, it should not make gross mistatements such as found on page 6: ie., Isotopes of the same element can have radically diverse chemical properties.
Chemical properties of an element are the result of the electronic arrangement of its' orbiting electrons.All isotopes of a particular element have the same orbiting electron arrangement, thus the same chemical properties.
The isotopes of a given element have different masses due to the different number of neutrons in their nuclei.For this reason, physical methods are used to separate the various isotopes of a given element.

A Wonderful Little Book!
Tiny and almost like a child's book, this puppy helped me catch up with all the new stuff that's been going on in the world of physics since I took the subject in high school decades ago. Only slightly larger than a CD jewel case and only 58 pages - and half of those are filled with diagrams - it still took me the better part of my Sunday morning to read and comprehend it. I was particularly impressed with the last page: a graphic representation of 36 different electron orbitals. I also liked the alternatives to the periodic tables that he offers. And his depiction of the universe since the Big Bang is enlightening. I finished the book amazed at how much of everything is nothing.

The author also has added a sense of playfulness to the diagrams (and occasionally, the text) that helps to keep this subject from turning into the snoozer it traditionally is. Now I know why all those nerdy, high-end mathematician-types are so passionate about their work!

If you take mass transit to work, this is an excellent book for you. ... Read more

Born in an isolated Siberian village in 1834, Dmitri Ivanovitch Mendeleyev overcame great odds to become the most brilliant and acclaimed scientist in the field of chemistry in the 19th century. His mother's determination overcame the objections of those who believed he was a poor student. She took him the long hard way across Siberia to Moscow and later St. Petersburg where finally Mendeleyev was admitted to a teachers college. Despite his mother's death and his own serious illness, he was awarded the gold medal for best student of the year in 1855. As a young chemistry teacher, he was sent to study in Europe in order the bring the latest developments in the science back to Russia. He succeeded so well that his chemistry textbooks became standard texts all over the world, and his Periodic Table of the Elements forms the foundation for all the advances in chemistry from his time until the present. ...

Great science mystery without being too scientific for lay people
Retired physicist Gloria Lamerino and her homicide detective fiancé Matt Gennaro are in Berkley, CA, to help her friend Elaine prepare for her wedding.Elaine's fiancé, Phil, is a fellow scientist, but he rubbed Gloria wrong from the minute she met him.

Phil's daughter's EMT work partner is shot dead by what is believed to be a mugger.Gloria is soon suspicious because of the information Phil seems to have about the shooting and the patient his daughter was helping transport when her partner was shot.

Gloria's suspicions of Phil soon alienate Elaine, but when Phil goes missing, everyone joins together to try to locate him.Plus Gloria is sure that this has something to do with his work and the shooting.Can she find him in time to save the wedding?

I really like Gloria.Even though she is a scientist, I don't feel these mysteries are written so that laymen can't understand even the scientific talk.I like that.This is a great cozy series that is such an easy read.

This one being set in California was fun.It was Gloria's old stomping grounds from years ago, so she knew people and places.Made it all more believable.I highly recommend this book and the series.

disappointing
As a retired chemist and fan of cozy mysteries I looked forward to what I thought based on the reviews would be a good new author with a scientific twist. This book is my first by Minichino. The involvement of Nitrogen in this was so superficial and sketchy as to look contrived. The two plots (nitrogen research and stolen medical supplies) wereloosely tied together and very poorly developed.The connection wasvery forced and not convincing. The development of all the male characters was very, very poor with little dialogue. They were all vaguely there, even Gloria's fiance. The only good spot and character was the "star" Gloria and she kept me reading. But, I kept wondering when is this all going to tie together and where is the substance?
In summary, though the book had its interesting parts the overall conclusion was dissatisfaction and the feeling that it was put together to meet a publishers deadline. I might look for an earlier episode in paperback, but definitely never pop for a hardcover again.

Two Murders, Stolen Drugs, Secret Nitrogen Files, and a Missing Scientist
Retired physicist Dr. Gloria Lamerino is visiting California with her fiance, Revere Police Detective Matt Gennaro.Gloria's best friend Elaine Cody is getting married in two weeks, and Gloria and Matt are in Berkeley to help with the celebration and have a little vacation.Just as soon as Gloria and Matt arrive in California, though, trouble strikes when they learn that Tanisha Hall, a young paramedic gunned down at the door to an Oakland hospital is the partner of Elaine's future daughter-in-law.The plot thickens when they learn that the patient being transported to the hospital (who later dies of his wounds) is an Indian scientist working on highly classifed research pertaining to powerful new explosives using newly discovered nitrogen molecules.Gloria and Matt begin to suspect that Elaine's fiance Phil Chambers might be involved in the two murders.When Phil suddenly disappears, no one is sure if he's just gotten cold feet about his wedding or if he is running from the law.

There's a lot of interesting and well-tied together plot lines in this book.In addition to the mystery of the two murders and the missing Dr. Phil Chambers, there are some missing drugs and medical supplies, stolen from the ambulance company, which are found in the murdered paramedic's home.As in all the stories in this series, author Minichino sprinkles in a healthy dose of scientific knowledge.The information she gives on newly found nitrogen compounds and their use in new powerful explosives is really fascinating.The characters in this series are well-developed and very believable.

Being a former resident of the California Bay area myself, I thoroughly enjoyed the Berkeley setting.Whether or not readers are familiar with the previous books in this series, I highly recommend "The Nitogen Murder" as a very entertaining mystery.

superb scientific mystery
Retired scientist Gloria Lamerino and her fiancé Matt Gennaro are in Berkley California to attend the wedding of her close friend scientist Elaine Cody to retired chemist Phillip Chambers, a consultant to Dorman Industries.Phil's daughter Dana is still traumatized by seeing her EMT partner gunned down while bringing their patient Lakesh Patel to the hospital.Mr. Patel dies in the hospital and the killer makes off with his duffel bag but Dana brings home his briefcase what contains severed ID's under different names including access to Dorman Industries.

When Phil and Gloria meet, she isn't impressed with him but her mild feelings of disdain turn to severe anxiety when Dana confides that somehow the briefcase wound up in her father's apartment.Patel and Phil collaborated on several papers involving nitrogen weapons research.When Phil disappears, Gloria and Matt work together to try and figure out the connection between the dead scientist, the stolen research and the multiple identifications that Mr. Patel carried.

There are very few mystery authors today who can incorporate a lot of scientific data into the story and make it part of a one sitting thriller as Camilla Minichino consistently does.She makes the science understandable so reader can learn while they are being entertained.The protagonist of THE NITROGEN MURDER is spunky, strong-willed and totally loyal to her friends, which endears her to the audience.The relationship between Gloria and Matt is believable and affirms that there is life after retirement.
