Molecular compounds cannot conduct electricity because they lack freely moving electrons. "acceptedAnswer": { When combining with another nitrogen atom to form a diatomic molecule, the three single electrons on each atom combine to form three shared pairs of electrons. Larger molecules can have many, many bonds that serve to keep the molecule together. When the atoms in a molecular compound make covalent bonds with one another in a specific arrangement, a molecule is created. These compounds are very different from ionic compounds like sodium chloride (NaCl). Most molecular compounds have relatively low boiling temperatures because the individual molecules of covalent compounds may be separated more readily than the ions in a crystal. Prefixes are used in the names of binary molecular compounds to identify the number of atoms of each element.

Organic compounds are compounds with carbon atoms and are named by a separate nomenclature system. In general, the elements that combine to form binary molecular compounds are both nonmetals. Atoms in molecular compounds form covalent bonds because they have similar electronegativities, which means that they have a similar attraction for electrons. Unlike ionic bonds, where electrons are either lost or gained by an atom to form charged ions, electrons in covalent compounds are shared between the two atoms, giving rise to properties that are quite different from those seen in ionic materials.
