History

Darmstadtium was first created in 1994, at the Institute for Heavy Ion Research (Gesellschaft für Schwerionenforschung) in Darmstadt, Germany, by Peter Armbruster and Gottfried Münzenberg, under the direction of Sigurd Hofmann. The team bombarded a lead-208 target with accelerated nuclei of nickel-62 and detected a single atom of the isotope darmstadtium-269. Named after the German city of Darmstadt

DiscoverersHeavy Ion Research Laboratory (HIRL)
Discovery LocationGermany
Discovery Year1994
Name OriginNamed after the city of Darmstadt, Germany where GSI Helmholtz Centre for Heavy Ion Research is located.
Darmstadtium is harmful due to its radioactivity
Darmstadtium has no stable or naturally-occurring isotopes

Uses

Darmstadtium is used for scientific research purposes only. It has no significant commercial applications.
