User:TyEvSkyo/Unbiunium

Unbiunium a hypothetical chemical element with the symbol Ubu and has the atomic number 121. nunennium and Uue are the temporary systematic IUPAC name and symbol, until a permanent name is decided upon. In the periodic table of the elements, it is expected to be a g-block element, and a superactinide metal. , no attempt has been made to synthesize unbiunium.

Naming
Using the 1979 IUPAC recommendations, the element should be temporarily called unbiunium (symbol Ubu) until it is discovered, the discovery is confirmed, and a permanent name chosen.

Electron configuration
Unbiunium is the first element whose ground state electron configuration may contain an electron in a g subshell, which would make it the first element in the g-block. However, neither lanthanum nor actinium show such a predicted ground state for the f-block and have their last electron occupying a d orbital, so unbiunium's third electron should also hang up. Other elements have access to their g subshells, though not in their ground states. Computations have indicated that the ground state of the element would be [Uuo]8s25g1.

Extrapolated chemical properties
Unbiunium is expected to behave similar chemically to lanthanum and actinium and 4f-block elements in general. A predicted oxidation state is III.
