The explanation of the results led to the birth of
Rutherford’s planetary model of atom (also called the
nuclear model of the atom) According to this the entire
positive charge and most of the mass of the atom is
concentrated in a small volume called the nucleus with electrons revolving
around the nucleus just as planets revolve around the sun Rutherford’s nuclear model was a major step towards how we see
the atom today However, it could not explain why atoms emit light of
only discrete wavelengths
