how many electrons are there in the highest occupied energy level of atoms in group 5a elements?
blank 1:

Explanation:

Step1: Understand group number and valence electrons

In the periodic table, for main - group elements (Groups 1A - 8A), the group number (in the A - group notation) gives the number of valence electrons (electrons in the highest occupied energy level).

Step2: Apply the rule to Group 5A

For Group 5A elements, using the rule that the group number (in A - group) equals the number of valence electrons.

Answer:

5
