Understanding the Melting Points: CaF2 vs. CaO

The melting point of Calcium Fluoride as compared to Calcium Oxide can be explained by Fajan's rules, aligning melting characteristics with ion charge distribution. Generally, higher charge leads to elevated melting points due to enhanced ionic character.

Within Fajan's framework, the interplay of effective nuclear charge and covalent character enables predictions about melting points based on ionic interactions. Larger ions yield reduced electrostatic effects, often lowering CaF2's melting point relative to other ionic compounds.

The ionic nature of compounds defines their thermal properties; for instance, while CaF2 shows lower melting points due to covalent characteristics, the comparative aspects of CaO must factor in ionic size and molecular structure.
