Aluminium Nitride Ionic Formula

Aluminium nitride is an ionic compound made up of aluminium cations (Al3+) and nitride anions (N3-).

The ionic formula for aluminium nitride can be determined by balancing the charges of the cation and anion to achieve a neutral compound. Since the aluminium cation has a charge of +3 and the nitride anion has a charge of -3, we need one of each ion to achieve balance.

Thus, the ionic formula for aluminium nitride is AlN, indicating that there is one aluminium cation and one nitride anion present in the compound.
