How It Works

Who arranged the periodic table and when?

The periodic table shows all the chemical elements which make up matter in an ordered and useful way. The current recognisable form began with a Russian scientist called Dmitri Mendeleev (1834-1907) in 1869. Mendeleev was a Russian chemist and inventor, and he was able to use the periodic table that he had created to successfully predict elements which had not then been discovered. Since then, many more elements have been predicted and discovered, totalling 118 at present.

Mendeleev was also famous for marrying a woman while he was still married to someone else, and for standardising the amount of alcohol in Russian vodka to 40%. Element number 101 (mendelevium), as well as the crater Mendeleev in the moon are named after him.

    Mendelevium is element 101, 107 is bohrium.

    • Apologies Warren, this has been changed.
