Question

A metal 'M' is divalent in its 'ous' state and trivalent in its 'ic' state. Write the formula of the Metal nitride.

Answer 1

The formula of the metal nitride in it's "ous" state can be written as follows:

$M^{+2}+N^{3-}\to M_3{N}_2$

The formula of the metal nitride in it's "ic" state can be written as follows:

$M^{+3}+N^{3-}\to MN$
