Description
This application is a SIMPLE periodic table of the chemical elements.

About
*****
The periodic table of the chemical elements is a tabular display of the chemical elements.
 Although precursors to this table exist,
 its invention is generally credited to Russian chemist Dmitri Mendeleev in 1869, who intended the table to illustrate recurring ("periodic") trends in the properties of the elements. 
The layout of the table has been refined and extended over time, 
as new elements have been discovered,
 and new theoretical models have been developed to explain chemical behavior.
