rdfs:comment	La valence d'un élément chimique est le nombre maximal de liaisons covalentes ou ioniques qu'il peut former en fonction de sa configuration électronique. Dans une molécule ou un ion, la valence d'un atome est le nombre de liaisons covalentes que cet atome a formées. Dans un ion monoatomique, sa valence est sa charge, on parle alors d'électrovalence. Un élément univalent est ainsi un élément qui formera des molécules en formant une seule liaison covalente ou des ions monochargés ; a contrario, les éléments bivalents, trivalents ou tétravalents s'associeront avec respectivement deux, trois ou quatre atomes d'un élément univalent pour former des molécules, comme dans le méthane (CH4) où le carbone, à valence quadruple, est lié à quatre atomes d'hydrogène.
