(ii) the largest atomic size?

Solution

(i) The bottom most element of the group will have the greatest metallic character because of the largest atomic size. The effective nuclear charge has the least effect on the valence electrons.

(ii) The bottom most element of the group will have the largest atomic size because on moving down the group, shells keep on adding to the electrons and this increases the size of the atom.
