Tenesin (117Ts) adalah unsur buatan yang paling baru disintesis, dan sebagian besar datanya bersifat hipotetis. Seperti semua unsur buatan, ia tidak memiliki satu pun isotop stabil, sehingga berat atom standarnya tidak dapat diberikan. Isotop pertama tenesin yang disintesis (dan sejauh ini hanya mereka) adalah 293Ts dan 294Ts pada tahun 2009. Isotop yang berumur paling panjang adalah 294Ts dengan waktu paruh 51 milidetik (0,051 detik).
