'''[[Erbium]]''' ('''68Er''') yang terbentuk secara alami terdiri dari enam [[isotop]] [[Isotop stabil|stabil]], dengan 166Er sebagai yang paling melimpah (33,503% [[Kelimpahan alami unsur|kelimpahan alami]]). 39 [[Radionuklida|radioisotop]] telah dikarakterisasi berkisar mulai dari 74 hingga 112 [[neutron]], atau 142 hingga 180 [[nukleon]], dengan yang paling stabil adalah 169Er dengan [[waktu paruh]] 9,4 hari, 172Er dengan waktu paruh 49,3 jam, 160Er dengan waktu paruh 28,58 jam, 165Er dengan waktu paruh 10,36 jam, dan 171Er dengan waktu paruh 7,516 jam. Semua isotop [[Peluruhan radioaktif|radioaktif]] yang tersisa memiliki waktu paruh kurang dari 3,5 jam, dan sebagian besar memiliki waktu paruh kurang dari 4 menit. Unsur ini juga memiliki banyak [[Isomer nuklir|keadaan meta]], dengan yang paling stabil adalah 167mEr (''t''1/2 2,269 detik).

Isotop erbium memiliki [[Massa atom relatif|berat atom]] berkisar mulai dari 141,9723 [[Dalton (satuan)|u]] (142Er) hingga 176,9541 u (177Er). [[Mode peluruhan]] utama sebelum isotop stabil yang paling melimpah, 166Er, adalah [[penangkapan elektron]], dan mode utama sesudahnya adalah [[peluruhan beta]]. [[Produk peluruhan]] utama sebelum 166Er adalah [[isotop holmium]], dan produk utama sesudahnya adalah [[isotop tulium]]. Semua isotop erbium bersifat radioaktif atau [[stabil secara pengamatan]], artinya mereka diprediksi bersifat radioaktif tetapi tidak ada peluruhan aktual yang teramati.
