Ununbium was discovered by S. Hofmann, V. Ninov, F. P. Hessberger, P. Armbruster, H. Folger, G. Münzenberg, and others at 1996 in Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany.. Origin of name: temporary systematic IUPAC nomenclature

Element 112 was discovered on 9th February 1996 at 22:37 at the GSI in Darmstadt, Germany. The identified isotope currently is the heaviest atom ever produced by man and has an atomic mass of 277, that is, 277 times heavier than hydrogen. The new element was produced by fusing a zinc atom with a lead atom. To achieve this, the zinc atom was accelerated to high energies by the heavy ion accelerator UNILAC at GSI and directed onto a lead target.
