उत्तर

Write the formula of

Magnesium nitride Symbol Valency
Magnesium \[\ce{Mg}\] \[\ce{2^{+}}\]
Nitride \[\ce{N}\] \[\ce{3^{-}}\]

Step I – Write each symbol with its valency.
Positive ion is written first
\[\ce{Mg}^{2+}\]  \[\ce{N}^{3-}\]
Step II – Interchange the valencies positive ion is written first.

The Formula is \[\ce{Mg3N2}\]
