jan 1, 1913 - Bohr

Description:

Proposed a theory for the hydrogen atom based on the quantum theory that energy is transferred only in certain well defined quantities. Electrons should move around the nucleus only in prescribed orbits. He made a new model that represented what the atom looks like and it is now called the Bohr model.
