Identify the compound with the highest magnitude of lattice energy. A) MgBr₂ B) BaBr₂ C) SrBr₂ D) CsBr₂

Question

Quizplus · Accepted Answer

MgBr2 has the highest magnitude of lattice energy because lattice energy increases with the charge of the ions and decreases with the size of the ions. Mg2+ has a higher charge and smaller size compared to Ba2+, Sr2+, and Cs+, leading to a stronger electrostatic attraction between the ions in MgBr2.
