1) The Bohr atomic model hypothesis made correct predictions for lower sized atoms like hydrogen, but poor spectrum predictions were achieved when larger atoms were taken into account. 2) When the spectral line is split into numerous components in the presence of a magnetic field, it fails to explain the Zeeman phenomenon.
