WebScience Chemistry In an ionic compound, the size of the ions affects the internuclear distance (the distance between the centers of adjacent ions), which affects lattice energy (a measure of the attractive force holding those ions together). Based on ion sizes, arrange these compounds by their expected lattice energy. Note that many sources define … WebApr 25, 2015 · Apr 25, 2015 (1) MgO has the highest lattice energy. Explanation: The lattice energy depends on the attraction between the oppositely charged ions. The force of attraction F is directly proportional to the charges ( q1 and q2) on the two ions and on the distance r between them. F = q1q2 r2
