Isotopes of ununoctium
From Wikipedia, the free encyclopedia
Ununoctium (Uuo) was only very recently synthesized; all data are theoretical. It has no stable isotopes. A standard atomic mass cannot be given.

- Values marked # are not purely derived from experimental data, but at least partly from systematic trends.
- Uncertainties are given in concise form in parentheses after the corresponding last digits. Uncertainty values from Ame2003 denote one standard deviation. Values from IUPAC are expanded uncertainties.
- Isotope masses from Ame2003 Atomic Mass Evaluation by G. Audi, A.H. Wapstra, C. Thibault, J. Blachot and O. Bersillon in Nuclear Physics A729 (2003).
