Magnesium nitride
Advertisements
Solution
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 \[\ce{Mg3N2}\]
