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