(this element does not have any stable isotopes)
Atomic weight of the most stable isotope: 293.20449(60) u
| Isotope | Atomic weight/u | Half-life |
| 290 | 290.19864(71) | 15 ms +26-6 |
| 291 | 291.20108(66) | 6.3 ms +116-2 |
| 292 | 292.20174(91) | 18 ms +16-6 |
| 293 | 293.20449(60) | 53 ms +62-19 |
Units: y = year, d = day, h = hour, m = minute, s = second, ms = millisecond, µs = microsecond.
Numbers in italics are uncertainties with the same unit as the last digit of the half-life.
Atomic weights were obtained from NIST Database 144
The half-life of radioactive isotopes was obtained from the Nuclear Wallet Cards
