When nitrogen and aluminum form an ionic bond, the formula of the ionic compound is AlN.

Aluminum forms a cation Al⁺³ and nitrogen forms an anion N⁻³. When each cation of Al⁺³ combines with an anion of N⁻³, AlN or aluminum nitride is formed. In AlN a strong electrostatic force of attraction exists between the oppositely charged Al⁺³ and  N⁻³ ions.

Answer:

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.
