Choose the correct alternative form the clues given at the end of each statement: (a) The size of the atom in Thomson's model is ........... the atomic size in Rutherford's model (much greater than/no different form/much less than) (b) In the ground state of ..........., electrons are in stable equilibrium, while in.......... electrons always experience a net force (Thomson's model/Rutherford's model). (c) A classical atom based on ......... is doomed to collapse (Thomson's model/Rutherford's model). (d) An atom has a nearly continuous mass distribution in ......... but has highly non uniform mass distribution in....... (Thomson's model/Rutherford's model). (e) The positively charge part of the atom possesses most of the mass of the atom in .......... (Rutherford's ,model /both the models).
