Thomson’s atomic model explained the overall neutrality of an atom. Its assumption that the total mass of an atom is uniformly distributed all over the atom was inconsistent with some experimental results. Rutherford’s gold foil experiment of scattering α-particles revealed that most of the space in an atom is empty contradicted Thomson’s atomic model. Thus, it was found that the plum pudding atomic model was insufficient to explain the structure of an atom.

The limitations of Thomson’s atomic model triggered further researches for establishing the structure of an atom.
