Bohr theory

Bohr theory

n.
An early model of atomic structure in which electrons travel around the nucleus in a number of discrete stable orbits determined by quantum conditions.

[After Niels Henrik David Bohr.]

Bohr theory

n
(Atomic Physics) a theory of atomic structure that explains the spectrum of hydrogen atoms. It assumes that the electron orbiting around the nucleus can exist only in certain energy states, a jump from one state to another being accompanied by the emission or absorption of a quantum of radiation
[C20: after Niels Bohr]

Bohr′ the`ory



n.
a quantum theory in which electrons move around an atomic nucleus in distinct circular orbits corresponding to quantized energy levels.
[1920–25; after N. Bohr]

The Bohr theory of the atom modified the way experiments were interpreted.
We might even suggest that the successes of the Bohr Theory for the atom, the Ballmer series formula for energy levels and indeed the Schrodinger equation itself in predicting discrete behaviour in atoms and other entities, might be mainly due to the discretization of space implied in their formulations.
Some examples of these are: the discovery of the radioactivity of thorium, and the new elements polonium and radium (1898); the identification of alpha and beta radiation (1899); the Rutherford/Soddy disintegration theory (1902); the discovery of isotopes (1909); the Rutherford nuclear theory of the atom (1911); the Bohr theory of the atom (1913); the disintegration of nitrogen atoms (1919); the discovery of artificial radioactivity (1933); and the discovery of nuclear fission (1938).
