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]
Thesaurus
Noun1.Bohr theory - (physics) a theory of atomic structure that combined Rutherford's model with the quantum theory; electrons orbiting a nucleus can only be in certain stationary energy states and light is emitted when electrons jump from one energy state to anothernatural philosophy, physics - the science of matter and energy and their interactions; "his favorite subject was physics"atomic theory - a theory of the structure of the atom

Bohr theory


Bohr theory

[′bȯr ‚thē·ə·rē] (atomic physics) A theory of atomic structure postulating an electron moving in one of certain discrete circular orbits about a nucleus with emission or absorption of electromagnetic radiation necessarily accompanied by transitions of the electron between the allowed orbits.

Bohr theory


Bohr the·o·ry

(bōr), that spectrum lines are produced 1) by the quantized emission of radiant energy when electrons drop from an orbit of a higher to one of a lower energy level, or 2) by absorption of radiation when an electron rises from a lower to a higher energy level.

Bohr the·o·ry

(bōr thē'ŏr-ē) Theory thatspectrum lines are produced 1) by the quantized emission of radiant energy when electrons drop from an orbit of a higher to one of a lower energy level, or 2) by absorption of radiation when an electron rises from a lower to a higher energy level.

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 magnetonBohr 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.
