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