Answer

Limitations of J.J. Thomson's model of the atom were:

  1. It failed to explain how the positive charge holds on the electrons inside the atom. It also failed to explain the stability of an atom.
  2. The concept of the nucleus was not present in his model.
  3. It failed to explain the results of Rutherford's ∝–particle scattering experiment.
