Question

Lattice Energy The following compounds all display the NaCl structure. (i.e. They are isomorphous.) For each pair, indicate which would have the lattice energy of greater magnitude. OKI ORBI Osrs Srte sro Bao Naci Cao Case Ũ Ca0 Consider how the relative energies of interaction of "point" charges would vary with respect to the expected interionic distances, according to Coulomb's Law. (Detailed calculations should NOT be required to make these comparisons -- but consider, for example, the relative effects of doubling the charges, as compared to increasing the interionic distances.)

Answer 1
