The Bohr Atomic model of the atom was the first to incorporate quantum theory and was the forerunner of entirely quantum-mechanical models. It represented a significant break from earlier, classical ... The Bohr model of the atom was proposed by Neil Bohr in 1915. It came into existence with the modification of Rutherford’s model of an atom. Rutherford’s model … See more Bohr theory modified the atomic structure model by explaining that electrons move in fixed orbitals (shells) and not anywhere in between and he also explained that each orbit (shell) has a fixed energy. Rutherford explained the nucleus … See more Bohr’s theory is applicable to hydrogen-like species containing one electron only e.g. Li2+.
