jun 28, 1922 - Niels Bohr - Bohr Atomic Model (1922)

Bohr's model of an atom consisted of a small, positively charged nucleus surrounded by electrons in orbit. He was the first to discover this orbital motion of electrons as well as the fact that the number of valence electrons an element has determines its properties.
