Unter Selen-Isotope werden alle Atomkerne des chemischen Elements Selen zusammengefasst; diese bestehen allesamt aus einem Atomkern mit 34 Protonen und im ungeladenen Zustand aus 34 Elektronen. Der Unterschied zwischen den einzelnen Selen-Isotopen beruht auf der Anzahl der Neutronen im Kern.
Natürlich auftretende Selen-Isotope
Natürliche irdische Selen-Vorkommen setzen sich aus sechs verschiedenen Isotopen zusammen, die - mit Ausnahme des quasistabilen Selens 82 - als stabil gelten.
