Scientists bombarded lead-208 nuclei with zinc-70 nuclei in a heavy ion accelerator. A single atom of copernicium-277 resulted from the bombardment. Atoms of copernicium-281, copernicium-281 and copernicium-284 have been recorded more recently as decay products of flerovium. Classification: Copernicium is a transition metal)
