Isotopen van goud
Es Chemisches ElementGold (autsch), mit a Atommasse ab 196.966569(4) Sie, besitzt 1 Stall Isotop: 197Autsch. Es ist auch das einzige natürlich vorkommende Isotop dieses Elements, was es zu einem der mononuklidische Elemente. Gold ist daher das schwerste mononuklidische Element. Die 36 Radioisotope sind instabil und haben eine relativ kurze Halbwertszeit (meistens weniger als eins). zweite).
Das kurzlebige Isotop von Gold ist 171Au, mit einer Halbwertszeit von etwa 30 Mikrosekunden. Die langlebigste ist 195Au, mit einer Halbwertszeit von 186 Tage.
