a unit that is used to indicate the magnetic moment of the electron structure in an atom, equal to 9.27 × 10 −21 erg/gauss. Bohr magneton See under magneton.
(in the Bohr atom) the radius of the electron orbit having the lowest energy.
a theory of atomic structure in which the hydrogen atom (Bohr atom, ) is assumed to consist of a proton as nucleus, with a single electron moving in distinct circular orbits around it, each orbit corresponding to a specific quantized energy state: the theory was extended to other atoms. noun a theory of atomic structure […]
