The ability of an atom to form covalent bonds by sharing electrons with other atoms, or the number of such bonds an atom typically makes.
From 'co-' (together) + 'valence' (from Latin 'valentia,' meaning strength or capability). The term was created in early 20th-century chemistry to describe shared electron bonding.
Covalence is chemistry's democracy—instead of one atom dominating and stealing electrons, atoms share them equally in partnerships, which is why covalent compounds are so stable and common in living things.
