Answer: Answer to #1 is 3A and ns2np1

Answer to #2 is 4A and ns2np2

Explanation:Group number is the number of valance electrons and generic outer electron configuration has to add up to equal the number of valance electrons

The element in the first diagram is in group 13 while the element in the second diagram is in group 14.

The Lewis structure of an atom of an element is a representation of the number of valence electrons on the outermost shell of the atom of that element. Every group of elements have a generic electron configuration which represents the number of valence electrons contained by atoms of elements in that group.

In the first diagram, the element X belongs to group 3A(13) and has a generic outer electron configuration, ns2np1. In the second diagram, the element X is in group 4A(14) and has outer electron configuration ns2np2.
