Question

Chemical formula of Calcium nitride is $C{a}_3{N}_2$.

• A. True
• B. False

Answer 1

The correct option is A True

Chemical formula of Calcium nitride is $C{a}_3{N}_2$. Calcium ion is represented as $C{a}^{2+}$ and nitride ion is represented as $N^{3-}$. $+2$ charge on $C{a}^{2+}$ ion is balanced with $-3$ charge on $N^{3-}$ ion, when 3 $C{a}^{2+}$ ions combine with 2 $N^{3-}$ ions.
