To decide whether BaS or CaO has the greater lattice energy, we need to consider the relative sizes of the ions because both compounds contain a +2 metal ion and a −2 chalcogenide ion. Because Ba 2 + lies below Ca 2 + in the periodic table, Ba 2 + is larger than Ca 2 +. Similarly, S 2− is larger than O 2−.
