150 years ago, Russian chemist Dmitrii Mendeleev created the periodic table of the elements, revolutionizing chemistry.

Periodic Properties The crucial characteristic of Mendeleev’s system was that it illustrated a periodicity, or repetition, in the properties of the elements at certain regular intervals.

The periodic table of elements classifies elements according to patterns in properties. Elements in a group, or family, have similar properties.
