Formula of calcium nitride is "Caz N2". Explanation of Solution Given compound is calcium nitride. The given compound consists of calcium cation and nitride anion. Calcium belongs to Group 2A in periodic table and hence it forms Ca2+ cation. Nitrogen belongs to Group 5A and hence it forms N3- anion. In order for the ionic compound to be neutral, calcium ion and nitride ion has to be present in the ratio of 3: 2. Therefore, the formula of calcium nitride is Ca3N2.
