An approximation of the power of the bonds in an ionic compound can be acquired by calculating the lattice energy of the compound, which is the energy given off when contrasting charged ions in the gas stage come collected to create a solid. The lattice energy of the following compounds are:CsBr - 637CaO 3464KF 801

To arrange this from increasing:CsBr < KF < CaO.

The bigger the radius of an atom, the bigger the distance from one nucleus of the atom to the other in that molecule, therefore making a weaker bond which is a smaller magnitude lattice energy. This can be found in the periodic table.
