Why does it have to be made neutrual?

 

How does changing the desidnated +2 for Calcium changed to 3 make is more neutral?

 

How can you write this with roman numerals?

### Answer to Problem 74E **Formula of calcium nitride is "Ca₃N₂."** --- ### Explanation of Solution **Given compound is calcium nitride.** The given compound consists of calcium cation and nitride anion. Calcium belongs to Group 2A in the periodic table and hence it forms \( \text{Ca}^{2+} \) cation. Nitrogen belongs to Group 5A and hence it forms \( \text{N}^{3-} \) 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 \( \text{Ca}_3\text{N}_2 \).
