Bohr’s Theory of the Atom: Content, Closure and Consistency

WebIn 1913, Danish physicist Niels Bohr applied Max Planck’s quantum theory to the nuclear atom of Ernest Rutherford, thus formulating the well-known planetary model of the atom, wherein electrons orbit a central nucleus in well-defined levels of energy ( Figure 1 ). Note that Bohr stated that electrons in the atom follow elliptical orbits (not ... WebThe great Danish physicist Niels Bohr (1885–1962) made immediate use of Rutherford’s planetary model of the atom.
