Standard state (20 ^oC): solid

Discovery: 1984 Peter Armbruster, Gottfried Munzenber & GSI Darmstadt (DE)

Hassium was discovered by Peter Armbruster, Gottfried Munzenber (DE) and their co-workers at the Heavy Ion Research Laboratory (Gesellschaft fur Schwerionenforschung, GSI) in Darmstadt, Germany in 1984. The origin of the name is the Latin word Hassias meaning Hess, the German state. It is a synthetic radioactive metal. Hassium was produced by bombarding lead-208 with iron-58.
