Niels Bohr's explanation for the observation of atomic spectra was that electrons could only move in discrete energy steps within an atom. This led to the development of the Bohr model of the atom, which postulated that electrons could only exist in specific energy levels or orbitals, and that the emission or absorption of energy was due to electrons transitioning between these levels.
