Bohr at·om

(bōr),
a concept or model of the atom in which the negatively charged electrons move in circular or elliptic orbits around the positively charged nucleus, energy being emitted or absorbed when electrons change from one orbit to another.

Niels H.D., Danish physicist and Nobel laureate, 1885-1962.
Bohr atom - a concept or model of the atom in which the negatively charged electrons move in circular or elliptical orbits around the positively charged nucleus, energy being emitted or absorbed when electrons change from one orbit to another.
Bohr magneton - the net magnetic moment of one unpaired electron; used in electron spin resonance spectrometry for detection and estimation of free radicals. Synonym(s): electron magneton
Bohr theory - that spectrum lines are produced by the quantized emission of radiant energy when electrons drop from an orbit of a higher to one of a lower energy level, or by absorption of radiation when an electron rises from a lower to a higher energy level.

The Bohr model supposed that electrons orbit the nucleus in set orbitals or paths, and as energy was added to the atom the electrons made transitions between orbitals.

The Bohr model for the atom relies on an integral number of wavelengths around a circumference, which in this case can be interpreted as integral number of balls, which makes the present model more realistic and easier to digest.
