Select the compound with the highest lattice energy.

Question

Quizplus · Accepted Answer

The lattice energy of an ionic compound depends on the charge of the ions and the size of the ions. The greater the charge of the ions, the stronger the electrostatic attraction between them, leading to higher lattice energy. Similarly, the smaller the size of the ions, the closer they can pack together, leading to higher lattice energy. Among the given options, MgO has the highest lattice energy because it has the highest charge on its ions and the smallest size of its ions. Therefore, the answer is E.
