The ionic compound CaO crystallizes with the same structureas sodium chloride (Figure 8.3).

(b) Would energy beconsumed or released if a crystal of CaO was converted toa collection of widely separated Ca—O ion pairs? (c) Fromthe ionic radii given in Figure 7.8, calculate the potentialenergy of a single Ca—O ion pair that is just touching(the magnitude of electronic charge is given on the insideback cover). (d) Calculate the energy of a mole of such pairs.How does this compare to the lattice energy of CaO? (e)What factor do you think accounts for most of the discrepancybetween the energies in part (d)—the bonding in CaOis more covalent than ionic, or the electrostatic interactionsin a crystal lattice are more complicated than those in a singleion pair?
