The Periodic Table: A Field Guide to the Elements by Paul Parsons

As one of the most recognizable images in science, the periodic table is ingrained in our culture. First drawn up in 1869 by Dmitri Mendeleev, its 118 elements make up not only everything on our planet but also everything in the entire universe.

The Periodic Table looks at the fascinating story and surprising uses of each of those elements, whether solid, liquid or gas. From the little-known uses of gold in medicine to the development of the hydrogen bomb, each entry is accompanied by technical data (category, atomic number, weight, boiling point) presented in easy-to-read headers, and a colour-coding system that helps the reader to navigate through the different groups of elements.

A remarkable display of thought-provoking science and beautiful photography, this guide will allow the reader to discover the world afresh.

Periodic Table Explained: Introduction

Periodic Table

By Joshua Howgego. RUN your fingers over the white keys of a piano. The notes get higher and higher as your hand moves to the right. On the eighth key, something beautiful happens: a note hangs in the air that embodies something of the first, only with a different pitch. We began to twig that something similar was going on with the chemical elements more than years ago.

A good periodic table is a necessary part of every chemist's, or future chemist's, reference materials. After looking around for a useful printable periodic table, I found that most were pretty basic and included only a few properties. If you typically work with a different set of properties, you can download the spreadsheet and add in your own numbers. You will need to use a nice laser printer because the text is quite small. You may print and distribute as many paper copies of these periodic tables as you want to, as long as they are printed as-is. Note that photocopies don't turn out well.

As early chemists worked to purify ores and discovered more elements, they realized that various elements could be grouped together by their similar chemical behaviors. One such grouping includes lithium Li , sodium Na , and potassium K : These elements all are shiny, conduct heat and electricity well, and have similar chemical properties. A second grouping includes calcium Ca , strontium Sr , and barium Ba , which also are shiny, good conductors of heat and electricity, and have chemical properties in common. However, the specific properties of these two groupings are notably different from each other. For example: Li, Na, and K are much more reactive than are Ca, Sr, and Ba; Li, Na, and K form compounds with oxygen in a ratio of two of their atoms to one oxygen atom, whereas Ca, Sr, and Ba form compounds with one of their atoms to one oxygen atom.

An interval in square brackets provides the lower and upper bounds of the standard atomic weight for that element. For users needing an atomic-weight value for an unspecified sample with disregard to the uncertainty, the conventional values are provided. No values are listed for elements which lack isotopes with a characteristic isotopic abundance in natural terrestrial samples. Holden, Tyler B. By virtue of its work in relation with the chemical elements, IUPAC can dispense a periodic table that is up-to-date. IUPAC involvement covers various aspects of the table and data that it unveils, and several reports and recommendations, some quite recent, attest of that input.

This pictorial periodic table is colorful, fun, and packed with information. In addition to the element's name, symbol, and atomic number, each element box has a drawing of one of the element's main human uses or natural occurrences. The table is color-coded to show the chemical groupings. It does not overload kids with a lot of detailed numbers, like atomic weights and valence numbers. Note: Elements in Pictures and Elements in Words are a set. Either may stand alone, but they work best together.

The elements in the periodic table are arranged in order of increasing atomic number. All of these elements display several other trends and we can use the periodic law and table formation to predict their chemical, physical, and atomic properties. Understanding these trends is done by analyzing the elements electron configuration; all elements prefer an octet formation and will gain or lose electrons to form that stable configuration. We can never determine the atomic radius of an atom because there is never a zero probability of finding an electron, and thus never a distinct boundary to the atom. All that we can measure is the distance between two nuclei internuclear distance. A covalent radius is one-half the distance between the nuclei of two identical atoms.
