L'étain est l'élément chimique de numéro atomique 50, de symbole Sn (du latin stannum). C'est un métal pauvre du groupe 14 du tableau périodique. Il existe dix isotopes stables de l'étain, principalement ceux de masses 120, 118 et 116. L'étain existe aux états d'oxydation 0, +II et +IV. À température ambiante le corps simple étain est un solide métallique. L'étain est connu dès l'Antiquité, où il servait à protéger la vaisselle de l'oxydation et pour préparer le bronze. Il est toujours utilisé pour cet usage, et pour le brasage. Cet élément est peu toxique. Rare à l'état natif, l'étain est essentiellement extrait d'un minéral appelé cassitérite où il se trouve sous forme d'oxyde SnO2.
