Place the following in order of increasing magnitude of lattice energy.
MgO LiI BaS

Question

Quizplus · Accepted Answer

Lattice energy increases with the charge of the ions and decreases with the size of the ions. MgO has the highest lattice energy due to the +2 and -2 charges and smaller ionic sizes. BaS has lower lattice energy than MgO due to larger ionic sizes, and LiI has the lowest lattice energy due to the +1 and -1 charges and larger ionic sizes.
