WebJul 23, 2024 · Lattice energy is the result of electrostatic attraction between ions, and because these attractive forces decrease with increasing distance between ions, the … WebOct 4, 2024 · The simplified form of Coulomb’s law is used to calculate the lattice energy of ionic compounds. U = − k Q 1 Q 2 r. In this formula, U depicts the lattice energy of the ionic compound. Q 1 and Q 2 are the positive and negative ions of the compound. r represents the internuclear distance of the ions. And k is the proportionality constant.
