families have commonalities. Explain using as many answer choices that would apply.
A)
When forming compounds they become positive ions.
B)
As nonmetals, they have high electron affinities.
C)
These elements form covalent bonds when combining with metals
D
They gain or share electrons when they react with other elements,
E)
