However, he is remembered for his search for a pattern in inorganic chemistry. Just four years before Mendeleev announced his periodic table, Newlands noticed that there were similarities between ...

The first periodic table to become generally accepted was that of the Russian chemist Dmitri Mendeleev in 1869: he formulated the periodic law as a dependence of chemical properties on atomic mass.

The laws of chemistry Mendeleev (1834-1907) created his early periodic table in 1869. He took the 63 known elements and arranged them into a table, mainly by their atomic mass. Although he wasn't ...
