Consider two ionic compounds NaCl and BaO. Both materials have the same crystal structure where each ion is coordinated by six neighbors of opposite polarity (fcc rocksalt structure). In light of the ionic radii below properties (1) calculate the attractive bonding forces between the different ions, (2) compare qualitative curves of bond energy vs. ion separation distance for the two compounds (3) compare at least three properties you would expect to be different (and how so) for these two compounds. Compound cation radius anion radius Lattice Energy NaCl 0.126 nm 0.181 -786 KJ/mol BaO 0.136 0.140 -3054 KJ/mol
