Sejarah
Roentgenium was first synthesized by an international team led by Sigurd Hofmann at the Institute for Heavy Ion Research (Gesellschaft für Schwerionenforschung) in Darmstadt, Germany in 1994.

The team bombarded a target of bismuth-209 with accelerated nuclei of nickel-64 and detected a single atom of the isotope roentgenium-272.
