Izotopi de argint

Versiunea actuală a paginii nu a fost încă examinată de colaboratori experimentați și poate diferi semnificativ de versiunea revizuită pe 8 iunie 2019; verificările necesită 2 modificări .

Izotopii de argint sunt varietăți de atomi (și nuclee ) ale elementului chimic argint , având un conținut diferit de neutroni în nucleu. Argintul natural este un amestec de doi izotopi stabili ( 107 Ag și 109 Ag). Cel mai lung izotop radioactiv al argintului este 105 Ag cu un timp de înjumătățire de 41,3 zile, dar izomerul nuclear 108m Ag are un timp de înjumătățire de 439 de ani.
