Which compound has the higher lattice energy?
A.MgO
B.NaCl
C.KBr
D.LiCl
Explanation
Core Concept
MgO pairs 2+ and 2− ions, quadrupling the Coulombic attraction compared with +1/−1 salts. Its small ions also pack tightly, giving one of the largest lattice energies among common compounds.
Correct Answer
AMgO
