REVIEW: Predicting Ionic Bonds & Formulas

What is the ionic compound that is formed when you combine Li and N?

• LiN

• LiN₃

• Li₃N₂

• Li₃N

Answer explanation

Lithium has 1 valence electron, Nitrogen has 5. So nitrogen must steal 3 total to become stable; this means it must bond with 3 Li atoms.
