Untrinilium is the chemical element with the atomic number 130 which has not yet been detected. Since there are no natural isotopes of this element , it would have to be produced (synthesized) in an artificial way by nuclear fusion . The name is preliminary and is derived from the ordinal number. Untrinilium is possibly the tenth element to have a g orbital and is likely to have the electronic configuration [Og] 8s ² 8p ² 6f ³ 5g ⁵ . In the extended periodic table it belongs to the transactinoids ( it is not shown in the "normal" periodic table ).
