The Chemistry Division's Periodic Table describes the history, properties, resources, uses, isotopes, forms, costs, and other information for each element The Periodic table can be divided into nine families of elements each having similar properties. The families include: Alkali metals. The alkali metals, found in group 1 of the periodic table, are highly reactive metals that do not occur freely in nature. These metals have only one electron in their outer shell The Periodic Table contains 83 of the stable elements. It measures approximately 4.5 x 6 x 1 (114mm x 152.4mm x 25.4mm) They come with a micro fiber bag for storage. They also come with a certificate of authenticity that tells a little about each sample.

Electronegativity (EN) has been redefined as the average valence electron energy (AVEE) that takes into account all of the s and p electrons in the valence shell for main group elements. This definition confers unambiguous physical meaning on the term electronegativity. EN and AVEE can be used interchangeably, directly relating the parameter to the periodicity of the elements Sep 1, 2016 - The periodic table has transcended the role of being merely a means to graphically represent the elemental and atomic nature of matter.
