History

Ununbium was first created on February 9, 1996 at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany.

It's Elemental - The Element Ununbium (91 words)
Ununbium was first produced by Peter Armbruster, Gottfried Münzenber and their team working at the Gesellschaft für Schwerionenforschung in Darmstadt, Germany on February 9, 1996.
Ununbium's most stable isotope, ununbium-285, has a half-life of about 10 minutes.
Since only a few atoms of ununbium have ever been produced, it currently has no uses outside of basic scientific research.
