    Compare the radii of two species X and Y. Give reasons for your answer. (a) X has 12 protons and 12 electrons (b) has 12 protons and 10 electrons

Answer:

                  Since, species X has 12 protons and 12electrons, it is electrically neutral. Since, species Y has 12 protons and 10 electrons, therefore, it has two units positive charge. The electronic configuration of the two species are Species X                             Species V K LM                                      K L 282                                         28 Since, species X has three shells white species Y has two shells, therefore, species Y has smaller radius than species X.
