7. Divalent ionic crystals. Barium oxide has the NaCl structure. Estimate the cohesive energies per molecule of the hypothetical crystals Bato and Ba++o referred to separated neutral atoms. The observed nearest-neighbor internuclear distance is Ro = 2.76 Å; the first and second ionization potentials of Ba are 5.19 and 9.96 eV; and the electron affinities of the first and second electrons added to the neutral oxygen atom are 1.5 and -9.0 eV. The first electron affinity of the =
