ununennium

Pronounced: /ˌju nəˈnɛniəm/
A temporary systematic name for the hypothetical chemical element with the atomic number 119 and the symbol Uue, assigned by IUPAC. Ununennium is expected to be the first element in the eighth period of the periodic table and a member of the alkali metal group. Its properties have not been observed and are currently predicted only through theoretical models. If discovered and confirmed, it will receive a permanent name.
Scientists continue to theorize about the potential chemical behavior of ununennium.
• If ununennium is successfully synthesized, it will extend the periodic table into a new period.
