difference between rutherford and bohr model

In the Bohr model of the atom, electrons travel in defined circular orbits around the nucleus. Later on, a physicist put forth another principle called Heisenbergs uncertainty principle, which explains the impossibility of the simultaneous determination of exact position and momentum of small moving particles such as electrons. However, Bohr gave Rutherfords atomic model a shell structure in which electrons correspond to specific orbits with a discrete energy level.
