We’re being asked to determine the ionic compound with the highest melting point.


Recall that the melting point of an ionic compound is related to its lattice energy

The lattice energy can be estimated using:


lattice energy=cation charge×anion chargecation period # + anion period #



This means the compound with the highest lattice energy has the highest melting point.
