History

It was first created on the February 9, 1996 at the Gesellschaft f�r Schwerionenforschung (GSI) in Darmstadt, Germany. This element was created by fusing a zinc atom with a lead atom by accelerating zinc nuclei into a lead target in a heavy ion accelerator.

It is named Ununbium, as in 1-1-2-ium, a temporary IUPAC systematic element name. There is an ongoing element naming controversy over what this element should be called.
