歷史
Copernicium was first created on February 9, 1996, at the Institute for Heavy Ion Research (Gesellschaft für Schwerionenforschung) in Darmstadt, Germany, by Sigurd Hofmann, Victor Ninov et al.
This element was created by firing accelerated zinc-70 nuclei at a target made of lead-208 nuclei in a heavy ion accelerator.
A single atom of copernicium was produced with a mass number of 277.
