Bohr Model of atom: Neil Bohr in 1913 put forward a theory to develop atomic model and to overcome shortcomings of Rutherford model. Bohr theory has following postulates. Electrons revolve around the nucleus in fixed orbits (i.e. orbits of particular radii). Each orbit or shell is associated with a definite amount of energy. Electrons …

Atomic Model of Rutherford In 1911, Lord Rutherford made an experiment to construct an atomic model. He took a thin gold foil and bombarded it with α-particles. Gold foil was surrounded by photographic film. Rutherford’s Observations: He observed in the alpha scattering experiment that : Most α-rays passed through gold foil un-deflected. Only a …
