Both of these models advocated that the electron revolves around the nucleus and occupies a large space in an atom. The theory states that electrons are always traveling in the orbit shells or orbit around the nucleus. 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.
