WebCovalent compounds typically have lower melting and boiling points than ionic compounds. Key Terms. electronegativity: The tendency of an atom or molecule to attract electrons and thus form bonds. single bond: A type of covalent bond where only two electrons are shared between atoms. WebThe network solids have higher melting and boiling points because both metallic bonds and covalent bonds are very strong interactions. These strong interactions must be broken when the solid melts (or the liquid boils). It would require a lot of energy (high temperature) to break these interactions. LDFs are relatively weak interactions.
