Unbiunium

Unbiunium is not yet proven chemical element with atomic number 121

His name is preliminary and refers to the three digits of the order number. It may has the first element of the periodic system, a G- orbital, so that the tray 5 would be filled with an additional electron. Since no natural isotopes exist, there has yet to be generated artificially, through nuclear fusion.

In the extended periodic table it is among the Transactinoiden ( in "normal" periodic table it is not shown).
