Frantsium (87Fr) otxonasi yo'q izotoplar. A standart atom og'irligi berilishi mumkin emas. Uning eng barqaror izotopi 223Fr oralig'i sifatida izchil miqdorda uchraydigan 22 daqiqali yarim umrga ega Fr parchalanish mahsuloti ning 235U.

Eng barqaror izotoplari aniqlik bilan aniqlangan elementlardan fransiy eng beqaror hisoblanadi. Atom raqami 106 bo'lgan barcha elementlar (dengiz sudi ) yoki undan kattaroq eng barqaror izotoplar fransiyga qaraganda qisqaroq, ammo bu elementlarda nisbatan kam miqdordagi izotoplar mavjud. Ehtimol, ushbu elementlarning kashf qilinmagan izotoplari yarim umr ko'rishlari mumkin.
