Well I do know that a coordinate number is the number of atoms surrounding an atom in a solid state lattice And for the second bit, I assume LiCl would have a larger lattice energy due to the greater difference in electronegativity of both consituents, similar with the next one. Not sure...

How would I go about deriving the cooridinate numbers of both ions in rock salt, and, how could I account for the differences in lattice enthalpy between the following; LiCl (861 kJ/mole) - NaCl (787) LiCl - LiF (1046) LiCl - MgO (3850) Cheers.
