WebThe Niels Bohr Atomic Model theory is a model that was introduced by Niels Bohr in 1913 to describe the atom. It was a postulation of Bohr that the electrons rotated in a circular orbit around the nucleus of the atom. Niels Bohr’s atomic model was created based on previous research by Rutherford, Rutherford’s gold foil experiment, and ... WebPostulates of Bohr Atomic Model. Electrons revolve around the nucleus in a fixed circular path termed “orbits” or “shells” or “energy level.”. The orbits are termed as “stationary orbit.”. Every circular orbit will have a certain amount of fixed energy and these circular orbits were termed orbital shells. The electrons will not ...
