A) The size of the atom in Thomson's model is .......... the atomic size in Rutherford's 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. (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 a highly non-uniform mass distribution in ............ . (Thomson's model/Rutherford's model)
E) The positively charged part of the atom possesses most of the mass in ............. . (Rutherford's model/both the models)
Correct Answer: D
Solution :
| Option [d] is correct |
| Explanation: [a] The sizes of the atoms taken in Thomson's model is not different from the atomic size in Rutherford's model. |
| [b] In the ground state of Thomson's model, the electrons are in stable equilibrium, while in Rutherford's model, 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 highly non-uniform mass distribution in Rutherford's model. |
| [e] The positively charged part of the atom possesses most of the mass in both the models. |
