SUMMARY
The discussion focuses on deriving the coordinate numbers of ions in rock salt, specifically LiCl and NaCl, and comparing their lattice enthalpy values. The lattice enthalpy values provided are LiCl (861 kJ/mole), NaCl (787 kJ/mole), LiF (1046 kJ/mole), and MgO (3850 kJ/mole). A coordinate number is defined as the number of atoms surrounding a central atom in a solid-state lattice, and it is suggested that LiCl has a larger lattice energy due to the greater electronegativity difference between its constituents.
