Chapter 8 Notes
... Lattice energy increases with decreasing ionic radii. This makes sense if you think about it. After-all the smaller the ion, the closer the positive nucleus is to the valence electrons responsible for bonding. So Magnesium compounds will have higher (negative) lattice energies than Calcium compounds ...
