Roentgenium (111Rg) is a synthetic element, and thus a standard atomic weight cannot be given. Like all synthetic elements, it has no stable isotopes. The first isotope to be synthesized was 272Rg in 1994, which is also the only directly synthesized isotope; all others are decay products of nihonium Roentgenium. From its position in the periodic table, in group 11 below gold, this element should have the physical properties of a noble metal and, were it long enough lived it should be possible to make compound of it although, like gold, it might be reluctant to form them. Roentgenium is an extremely radioactive chemical element with symbol Rg and atomic number 111.

Roentgenium is calculated to have similar properties to its lighter homologues — copper, silver and gold — although it may show some differences as well. It is predicted to be a noble metal, and it is expected to be a solid under normal conditions and to crystallize in the body-centered cubic structure.
