Roéntgénium silih tunggil datu kimia sintétik antuk simbol Rg miwah wilangan atom 111. Punika datu sané sanget radioaktip wantah prasida kakardi ring laboratorium menawi nénten katemuin ring palemahan. Isotop pinih tegteg punika, roéntgénium-282, ngelah prauh idup of 100 detik, yadiastun durung kakonpirmasi roéntgénium-286 minab ngelah paruh idup luwih lantang punika 10.7 menit.[14] Roentgenium kapertama kakardi warsa 1994 olih Pusat GSI Helmholtz antuk Panelitian Ion Baat nampek Darmstadt, Jérman. Punika kaaranin saking fisikawan Wilhelm Röntgen (taler kawacén Roéntgén), sang sané nemuin Sunar-X.[15] Wantah makudang atom roéntgénium sané polih kasintésis, miwah sané mangkin kantun kateliti.[16]
