In almost all cases, it requires energy to break a compound down to its constituent elements. There are, however, some cases in which the decay of a compound into its constituent elements would release energy. Platinum hexafluoride would be an example.

A great deal of energy is produced when an ionic compound is formed?

False. Formation of a compound is usually exothermic because a Noble Gas configuration forms around each atom. Therefore energy is given off during formation, and the atoms in the compound are more stable.
