Exercise on Energetics of Ionic Bond Formation: Solutions

Question: Which substance would you expect to have the greatest lattice energy: AgCl, CuO, CrN

Solution:
Answer: E₁ = κ(Q₁Q₂)/d
Charge on the cations/anions of each compound is the main parameter that will determine the greatest lattice energy.
CrN (has Cr³⁺ and N³⁻), hence greatest lattice energy.
