1 jan 1913 ano - Bohr's Planetary Model

Descrição:

Discovered that electrons are on fixed orbits, and can jump between orbits. This shows that atoms will be completely stable in the state with the smallest orbit, because there is no orbit of a lower energy level where the electron can jump. Rutherford's Model/Experiment are related to this event.
