Bohr's energy equation
http://alpha.chem.umb.edu/chemistry/ch115/carter/files/103more/BohrEquations.pdf WebThe great Danish physicist Niels Bohr (1885–1962) made immediate use of Rutherford’s planetary model of the atom. (Figure 1). Bohr became convinced of its validity and spent part of 1912 at Rutherford’s laboratory. In 1913, after returning to Copenhagen, he began publishing his theory of the simplest atom, hydrogen, based on the planetary ...
