$(a)$ The sizes of the atoms taken in Thomson's model and Rutherford's model have the same order of magnitude.

$(b)$ In the ground state of Thomson's model, the electrons are in stable equilibrium. However,in Rutherford's model, the electrons always experience a net force.

$(c)$ A classical atom based on Rutherford's model is doomed to collapse.

$(d)$ An atom has a nearly continuous mass distribution in Thomson's model, but has a highlynon-uniform mass distribution in Rutherford's model.

$(e)$ The positively charged part of the atom possesses most of the mass in both the models.
