Plisg electronau coperniciwm
Elfen gemegol ymbelydrol sydd â'r symbol **Cn** a'r rhif atomig 112 yw **coperniciwm**. Mae'n elfen synthetig a grëwyd am y tro cyntaf ym 1996 gan y Gesellschaft für Schwerionenforschung (GSI) yn Darmstadt, yr Almaen. Roedd ganddo'r enw dros dro **ununbiwm** (**Uub**) tan 19 Chwefror 2010 pan fabwysiadwyd yr enw coperniciwm yn swyddogol. Fe'i henwyd ar ôl y seryddwr o Bwyliad Nicolaus Copernicus.
