Cao has high melting point
Did you know?
WebComparison of melting points of ionic compounds is generally done by considering the following two factors: 1. Charge of the cation/anion : More the charge of cation or anion, stronger will be the forces of attraction between the ions and higher will be the melting point. In this case, the charge is same as they belong to the same group.
