When nitrogen and aluminum form an ionic bond, what is the formula? (2 points)

The formula of ionic compound will be AlN.

Explanation:Ionic bond is bond between two atoms by permanently giving of valence electrons to get stability.Actually one atom gives electron to other. By which Donor atom become positive ion while recipient become negative ion.Then they are attracted towards each other by electrostatic force of attraction.Nitrogen needs 3 electron to fill the outer shell.While aluminium has 3 electrons in valence shell.So Al gives its 3 electron s to nitrogen.Al becomes positive ion and N becomes negative ion.Both attracts each other forming AlN molecule.
