Which of the following metals (M) will form an ionic compound with nitrogen with the general formula [tex]$M_3N_2$[/tex]?

Hint: Think about how many positive charges you need to balance out the negative charges from nitrogen.

Answer :

Final answer:

Metals such as aluminum, chromium, and iron could form an ionic compound with nitrogen with the general formula M3N2.

Explanation:

In order for a metal to form an ionic compound with nitrogen with the general formula M3N2, the metal must have a charge of +3. This is because nitrogen, as a nonmetal, has a charge of -3. Therefore, metals such as aluminum (Al), chromium (Cr), and iron (Fe) could form an ionic compound with nitrogen. The resulting formula for the compound would be Al3N2, Cr3N2, or Fe3N2, respectively.
