The Total solution for NCERT class 6-12
Choose the correct alternativefrom the clues given at the end of the each statement:
(a) The size of the atom in Thomson’smodel is .......... the atomic size in Rutherford’s model. (much greaterthan/no different from/much less than.)
(b) In the ground state of ..........electrons are in stable equilibrium, while in .......... electrons alwaysexperience a net force.
(Thomson’smodel/ Rutherford’s model.)
(c) A classical atombased on .......... is doomed to collapse.
(d) An atom has a nearly continuousmass distribution in a .......... but has a highly non-uniform massdistribution in ..........
(e) The positively charged part ofthe atom possesses most of the mass in .......... (Rutherford’s model/both themodels.)
(a) Thesizes of the atoms taken in Thomson’s model and Rutherford’s model have thesame order of magnitude.
(b) In the ground state of Thomson’smodel, the electrons are in stable equilibrium. However, in Rutherford’s model,the electrons always experience a net force.
(c) A classical atombased on Rutherford’s model is doomed to collapse.
(d) An atom has a nearly continuous massdistribution in Thomson’s model, but has a highly non-uniform mass distributionin Rutherford’s model.
(e) The positively charged part of the atompossesses most of the mass in both the models.
