It was first created at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany on December 8, 1994. Only three atoms of it have been created (all Uuu-272), by the fusion of bismuth-209 and nickel-64 in a linear accelerator (nickel was bombarded onto the target).
It is named Unununium, as in 1-1-1-ium, a temporary IUPAC systematic element name. There is an ongoing element naming controversy over what this element should be called.
