The Periodic Table of the Elements

The Periodic Table of the Elements is a chart of chemical elements arranged according to a scientific law called the periodic law.

Credit for inventing the periodic table is given to Russian scientist Dmitri Mendeleev who, in 1869, devised the table to illustrate recurring or periodic trends in the properties of the elements.

In chemistry, an element is substance supposed to be a simple body.

Mendeleev’s original├»┬┐┬Żarrangement has been adapted to accommodate new discoveries, but it remains an amazing framework for classifying chemical behavior. Gaps in the table remain for elements not yet discovered. So far, the table contains 118 elements, twice the number in the original.
