Table des isotopes

Restez toujours informé : suivez-nous sur Google (☆)

Voir aussi la table divisée des isotopes pour une lecture plus facile.

Cette table répertorie tous les isotopes connus des éléments chimiques, ordonnés selon leur numéro atomique croissant de gauche à droite et avec un nombre croissant de neutrons de haut en bas.

Les demi-vies sont indiquées par la couleur de la cellule de chaque isotope ; les isotopes ayant deux modes de désintégration qui diffèrent par leur demi-vie ont des couleurs de fond et de bordure différentes.
