A materials scientist compares the melting points of various ionic solids. Which compound exhibits the highest lattice energy due to greater ionic charges?
Q1. A materials scientist compares the melting points of various ionic solids. Which compound exhibits the highest lattice energy due to greater ionic charges?
Answer: MgO
Explanation: MgO has higher lattice energy due to +2/-2 charges; NaCl is tempting but its +1/-1 charges result in weaker electrostatic attraction.
