| In a covalent diatomic molecule, a difference in the electronegativity of the atoms will result in a dipole moment. |
| In covalent halides, such as carbon tetrachloride, the bonding electrons are localized in the carbon-chlorine bonds of the individual molecules. |
| The C-Cl bond is polar covalent, Na-Cl is ionic, and the C-C bond is pure covalent with each atom sharing the bonding electrons equally. |
| The particles have functional sites for forming a hydrogen bond or a coordinate covalent bond. |
| Electronegativity can be used to predict whether a bond will be a nonpolar covalent bond, a polar covalent bond, or an ionic bond. |
| The group III and IV elements, on the other hand, tend to form covalent halides. |
