(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 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.

When seen in the Bohr model, one can understand energy levels of the electrons and their movements around the nucleus, whereas the quantum mechanical view of an atom helps understand the possible location of electrons in relation to the nucleus.
Neutral hydrogen atoms in the Bohr model are represented with the nucleus at the center and an electron in orbit around the nucleus.
The cross section of neutral hydrogen as given by the Bohr model for an electron in orbit around the nucleus is 8.

It was widely accepted that the Bohr model contained substantial flaws.
The orbital radius of the electron remains substantially constant irrespective of the energy level of the atom, a necessary condition for an objectively real electron, and so transitions from one energy state to another take place without the need to introduce the idea of discontinuity of position, inherent in the Bohr model, or its equivalent probability density functions and wave particle duality found in other more recent models.
The Bohr model, and indeed the standard model, would have us believe that the morphology of the atom changes substantially with energy level, with the orbital radius increasing as the square of the energy level with no theoretical upper limit.
