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.

Bohr,

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.

One--often celebrated as the crucial ingredient in the Bohr atom model--declared that electrons could occupy only certain specific orbits around the nucleus.
At first site it appears that the energy of the electron in the Bohr atom decreases with increasing energy level.
His treatment of the Bohr atom, for instance, is pre-1925, he still believes in electronic planetary orbits.
