Covalency is a term used in chemistry to describe the extent to which two atoms share electrons to form a covalent bond. Synonyms for this term include bond strength, electron sharing, bonding capacity, and electron density. These synonyms refer to the same concept of the degree to which two atoms are bonded together by shared electrons. Another synonym for covalency is valence, which describes the number of electrons that an atom can bond with. In chemistry, understanding covalency is crucial to understanding the properties of molecules and their reactions. By using various synonyms for covalency, chemists can more accurately communicate about the nature of chemical interactions.
