Rutherford’s model of an atom was able to explain a lot about the structure of atom. Although it has a few drawbacks as well. The major drawback were it could not explain the stability of the atom. According to him, the electrons travelled in spiral orbits around the nucleus. But, if electrons followed the spiral path, then the electrons would loose the energy continuously and then, slowly they would fall in the nucleus. But, this does not happen, because atom is all stable and the electrons keep revolving in the circular orbits around the nucleus.
