'''[[Emas]]''' ('''79Au''') memiliki satu [[isotop]] [[Isotop stabil|stabil]], 197Au, dan 36 [[Radionuklida|radioisotop]], dengan 195Au menjadi yang paling stabil dengan [[waktu paruh]] 186 hari. Emas saat ini dianggap sebagai [[unsur monoisotop]] terberat. [[Bismut]] sebelumnya memegang gelar tersebut sampai [[peluruhan alfa]] dari isotop [[bismut-209|209Bi]] teramati. Semua isotop emas bersifat [[Peluruhan radioaktif|radioaktif]] atau, dalam kasus 197Au, [[stabil secara pengamatan]], yang berarti bahwa 197Au diprediksi bersifat radioaktif tetapi tidak ada peluruhan aktual yang teramati.

== Pembentukan dan kestabilan ==
Isotop emas yang terbentuk secara alami di alam memiliki [[nuklida stabil]] dan jumlahnya hanya satu. Sementara itu, puluhan isotop emas yang lainnya hanya dapat dibuat di [[laboratorium]] dan hasilnya merupakan [[Radionuklida|nuklida non-stabil]]. Kestabilan isotop emas agar berubah seiring waktu dan berakhir menjadi [[unsur kimia]] lain.
