Ionic Bonds/Covalent Intro

Question

Draw the Lewis structure for the ionic compound that forms from Al and N.

Please explain, too.

Answer 1

Al loses three valance electrons to become Al³⁺

N gains 3 electrons to become N^3-

The formula for the ionic compound being formed is AlN

The Lewis dot would be...

[Al³⁺] N^3-] and you'd put 4 pairs of electrons around the N atom
