Question

Place the following in order of decreasing magnitude of lattice energy. KF BaO RbI
A) RbI > KF > BaO
B) RbI > BaO > KF
C) BaO > RbI > KF
D) KF > RbI > BaO
E) BaO > KF > RbI

Quizplus · Accepted Answer

Lattice energy is influenced by the charge and size of the ions. BaO has the highest lattice energy because it involves ions with a +2 and -2 charge, leading to stronger attractions. KF comes next due to its smaller ions compared to RbI, which has the lowest lattice energy due to its larger ion sizes and +1 and -1 charges.
