Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds.
â¢ covalent bond: a bond formed when atoms share one or more pairs of electrons. â Compounds that are networks of bonded atoms, such as silicon dioxide, are al so covalently bonded. â Covalent bonds usually form between nonmetal atoms. Covalent Bonds, continued â¢ Covalent compounds can be solids, liquids, or gases.â In a chlorine molecule, Cl 2, the atoms share two electrons.â They are joined by one covalent bond. Covalent Bonds, continued â¢ Atoms may share more than one pair of electrons.
