Covalent compounds exhibit van der Waals intermolecular forces that form bonds of various strengths with other covalent compounds. If it is ionic, list the metal element first and then add the nonmetal element with the suffix "-ide. phosphorus (II) oxide e. Prefixes are used in the names of binary compounds to indicate the number of atoms of each nonmetal present. Both Hydrogen and Nitrogen share electrons among each other in order to complete their valence shells and become stable. In particular, the distance between the nuclei of the hydrogen and oxygen atoms of adjacent hydrogen-bonded molecules in water is approximately 0. The prefix mono is never used for naming the first element of a compound. Covalent bonds are intramolecular forces; that is, they are inside the molecule and hold the atoms together to make the molecule.
