Thomson' Model and Limitations

J.J. Thomson, in 1898, put forward his model of the atom. According to him, an atom is a positively charged sphere of radius about 10-10 m in which negatively charged electrons are uniformly embedded so as to have an overall electrically neutral atom.

Limitation of Thomson Model
Thomson's model of atom could account for the electrical neutrality of atom, but it could not explain the results of the 'gold foil scattering experiment' carried out by Rutherford.
