dec 30, 1912 - Neil Bohr: Quantum Model

Description:

In 1912, Neil Bohr created the Quantom Atomic Model, which stated that electrons did not lose their energy levels during rotation and that the chemcial properties of an elemnt could be determined by the amount of electrons that are in the outer orbits, leading to an electron cloud to possibly drop from one orbital to a lower one, causing the emition of a photon of energy.
