Solution

(a) The number of valence electrons in the outermost shell of an atom of an element is equal to the valency of an element.

(b) The number of valence electrons for all the elements in a group is the same. Therefore, the elements in the same group have the same valency.

(c) For example, the elements of Group I such as sodium (Na) and potassium (K) contain only one valence electron, and so, the valency of elements of Group I is one. Similarly, for Group II, the valency is two.
