Златото (79 Au) има еден стабилен изотоп, 197Au и 40 радиоизотопи, при што 195Au е најстабилен со полураспад од 186 дена. Златото во моментов се смета за најтешкиот моноизотопски елемент. Бизмутот порано ја држел таа разлика додека не било забележано алфа-распад на изотопот 209Bi. Сите изотопи на злато се или радиоактивни или, во случајот со 197Au, набљудувачко стабилни, што значи дека се предвидува дека 197Au е радиоактивен, но не е забележано вистинско распаѓање.
