Answer 2

Zinc has 30 electrons I.e. 28 in first three shells and 2 in the fourth. To achieve octet, it must either lose two electrons or gain six. Since it is easier to lose two electrons, Zinc loses these two electrons in the outermost shell and forms a 2+ action. Hence, valency of Zinc is two (2).
