We are being asked to identify which ionic compound has the highest lattice energy. To estimate the lattice energy (or ionic bond energy) of an ionic compound, we will use the following equation:
Radius = period number
• To determine the cation and anion charge, recall that some elements have common charges based on what group they belong to on the periodic table:
Which of these ionic solids would have the largest magnitude lattice energy?
A. KF B. CaBr2 C. NaF D. MgO E. CaI2
