Discovery: 1981 Peter Armbruster, Gottfried Münzenber & GSI Darmstadt (DE)
Bohrium was discovered by Peter Armbruster, Gottfried Münzenber (DE) and their co-workers at the Heavy Ion Research Laboratory (Gesellschaft für Schwerionenforschung, GSI) in Darmstadt, Germany in 1981. Named in honour of Niels 'Bohr', the Danish physicist. It is a synthetic radioactive metal. Bohrium was produced by bombarding bismuth-204 with chromium-54.
