The numerical value for the calcium oxide lattice energy based on the
Born-Haber cycle and the theoretical value based on calculation are very similar.
However, there is an 8% difference between the values for calcium iodide, with
the Born-Haber cycle value being more negative.
Compare the bonding in calcium oxide with that of calcium iodide and explain
fully why there is a significant difference between the experimental and
theoretical lattice energy values for calcium iodide

Have you thought about the polarisability of the anions?
