SUMMARY
The discussion centers on the hardness comparison among NaF, NaI, MgF2, MgI2, and CaI2, concluding that MgF2 exhibits the greatest hardness. The hardness is influenced by the strength of ionic bonds, which are determined by Coulombic forces, specifically the charges of the ions and the distances between them. Participants suggest focusing on the ionic radii and charge density of the ions to understand the underlying reasons for MgF2's superior hardness.
