The Periodic Table

All of chemistry starts with the periodic table of the chemical elements. The periodic table, first devised in 1869 by Dmitri Mendeleev, is a tabular framework for classifying and displaying the chemical elements and hence their chemical properties and behavior. The periodic "law" of chemistry recognises that properties of the elements are periodic functions of their atomic number. The periodic table orders the elements by atomic number in columns (groups) and rows (periods) in a way that emphasizes their periodicity.

The standard form of the table is presented here. By clicking on an element in the table, some attributes of the elements displayed. There are currently 116 confirmed elements, and two further speculated ones.
