# Isotopi dell'oro

In questa voce sono elencati tutti gli isotopi dell'oro (Au), che partono dall'oro-169($^{169}$Au) (peso circa 169 uma) e vanno fino all'oro-205($^{205}$Au). L'unico isotopo stabile dell'oro è il $^{197}$Au che compone tutto quello che comunemente viene commercializzato ed ha una massa di 196,966569 uma, mentre quello radioattivo più stabile è il $^{195}$Au con un'emivita di 186 giorni.
Massa atomica standard: 196,96655 uma
