Discovery: 1996 Sigurd Hofmann & GSI Darmstadt (DE)

Copernicium was discovered by S. Hofmann (DE) et al. collaboration at the Heavy Ion Research Laboratory (Gesellschaft fur Schwerionenforschung, GSI) in Darmstadt, Germany in February 1996. Named in honour of Nicolaus Copernicus. It is a synthetic radioactive metal. It was created by bombarding the lead-208 nuclei with accelerated zinc-70 nuclei in a heavy ion accelerator.
