Isotop antimon

Antimon (51Sb) yang terbentuk secara alami terdiri dari dua isotop stabil, 121Sb dan 123Sb. Ada 35 isotop radioaktif buatan, yang paling lama berumur 125Sb, dengan waktu paruh 2,75856 tahun; 124Sb, dengan waktu paruh 60,2 hari; dan 126Sb, dengan waktu paruh 12,35 hari. Semua isotop lain memiliki waktu paruh kurang dari 4 hari, kebanyakan kurang dari satu jam. Unsur ini juga memiliki banyak isomer, yang berumur paling panjang adalah 120m1Sb dengan waktu paruh 5,76 hari.
