Which of the following metals (M) will form an ionic compound with nitrogen with the general formula M3N2?

a
lithium (Li)
b
sodium (Na)
c
aluminum (Al)
d
beryllium (Be)

Answer :

I think it’s a or b i am so not positive
I thinks it’s D since Be has a charge of 2+ and you are given the formula of M3N2. When you swap and drop the charge of N (3-) and the charge of Be (2+) you get M3N2
