Isotopes of ununseptium

Isotopes of ununseptium

Ununseptium (Uus) has not yet been synthesized; all data are theoretical. It has no stable isotopes. A standard atomic mass cannot be given.

Notes

* 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.
