The lattice energy for ionic crystals increases as the charge on the ions _____________ and the size of the ions __________________ .

Question

Quizplus · Accepted Answer

The lattice energy is directly proportional to the charges on the ions and inversely proportional to the size of the ions. As the charge on the ions increases, the lattice energy also increases because there is a greater attraction between the ions. Conversely, as the size of the ions increases, the lattice energy decreases because the distance between the ions increases, thus weakening the attraction between them. Therefore, choice B is correct as it reflects these trends.
