Which of the ionic compounds below would you expect to have the smallest least negative) lattice energy?

Question

Quizplus · Accepted Answer

Lattice energy is influenced by the charge and size of the ions involved. Smaller and more highly charged ions result in a more negative (larger magnitude) lattice energy. Among the given options, CaI2 involves a divalent cation (Ca2+) and a relatively large anion (I-), leading to a smaller lattice energy compared to the others, which involve either smaller anions or ions with the same charge.
