1 janv. 1913 - Niels Bohr
Description:
Niels Bohr proposed a theory that electrons move around the nucleus only in orbits a certain distance from the nucleus, with each distance, or level, having a certain amount of energy. When jumping from one orbit level to another with lower energy, a light wave is emitted. This went against the Rutherford model, because Bohr believed that if electrons moved sporadically, radiation would always be emitted from the atom.Ajouté au bande de temps:
