Answer:

all of them have seven valence electron

Jobisdone [24]2 years ago
8 0
Group 1 has 1 valence electron

Group 2 has 2 valence electrons

Group 3 has 3 valence electrons

Thus, they all give electrons instead of taking like a noble gas does when satisfying the octet rule.

All of these groups have positive charges (i.e., +1, +2, +3).
