Roentgenium Element Cube Heritage Personal Museum The sample of pottery inRoentgenium's atomic number is 111 and its symbol is Rg. It is an extremely radioactive synthetic element that can be created in a laboratory but is not found in nature. The most stable known isotope, roentgenium 282, has a half life of 100 seconds. It is named after the physicist Wilhelm Rntgen (also spelled Roentgen), who also discovered X rays. Only a few roentgenium atoms have ever been synthesized, and they contain no current practical
