12 oct. 1913 - Neil Bohr
Description:
Neil Bohr proposed a theory for the hydrogen atom based on quantum theory that energy is transferred only in certain well defined quantities. Electrons should move around the nucleus but only in some orbits. When jumping from one orbit to another with lower energy, a light quantum is emitted.Ajouté au bande de temps:
