As long as the individual atoms can form an octet of electrons from sharing electrons in a covalent bond, there's always a possibility. So nitrogen for example is a non-metal with 5 valence electrons and needs 3 more for an octet, and can form a variety of covalent bonds.

WebJul 30, 2024 · Polar and Nonpolar Covalent Bonds. There are two types of covalent bonds: polar and nonpolar. Nonpolar covalent bonds form between two atoms of the same element or between different elements that share the electrons equally. For example, an oxygen atom can bond with another oxygen atom to fill their outer shells.
