Danish physicist who proposed a successful quantum model of the atom in 1913. His model assumed that
(1) the electron exists on precise circular orbits around the nucleus,
(2) as long as an electron remains in one orbit, no energy is given off, and
(3) the angular momenta associated with allowed electron motion are integral multiples of
.
Bohr introduced the Correspondence Principle, which states that quantum mechanical formulas must reduce to the
classical results in the limit of large quantum number. He also advocated a probabilistic interpretation of
quantum mechanics known as the
Copenhagen Interpretation.
In 1922 he was awarded the
Nobel Prize in physics for this work.
