J.J. Thompson developed one of the first mathematical models of the atom. Ernest Rutherford's experiments verified the structure of the nuclear atom. Neils Bohr developed an accurate mathematical model of the hydrogen atom.
The modern periodic table, based on atomic number and electron configuration, was created primarily by a Russian chemist, Dmitri Ivanovich Mendeleev, and a German physicist, Julius Lothar Meyer, both working independently. They both created similar periodic tables only a few months apart in 1869. Mendeleev created the first periodic table based on atomic weight. He observed that many elements had similar properties, and that they occur periodically. Hence, the table's name. His periodic law states that the chemical and physical properties of the elements vary in a periodic way with their atomic weights.
