It takes a lot of energy to overcome the strong electrostatic forces of attraction between oppositely charged ions, so ionic compounds have high melting and boiling points. WebThese ions will be arranged in an ionic lattice structure. There is a strong attractive force between these oppositely charged ions, which require a lot of energy to break lots of these bonds to melt the lattice structure. This is why sodium oxide has a high melting point. Answered by • Chemistry tutor.
