118 Uuo Ununoctium

No stable and no natural isotopes.

Ununoctium

First made probably 2002 by bombarding californium with calcium, it decays to livermorium. Ununoctium isotopes have half-lifes of some milliseconds. The element belongs to the group of noble gases, but it maybe doesn't behave like one. A research about this wasn't possible so far, 2002 and 2005 only three atoms of it were made.
