Roentgenium's most stable isotope, roentgenium-281, has a half-life of about 26 seconds and decays through spontaneous fission. 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. Roentgenium (111Rg) is a synthetic element, and thus a standard atomic weight cannot be given.

The Roentgenium that is available is produced through nuclear … Meitnerium was first made in 1982 at the German nuclear research facility, the Gesellschaft für Schwerionenforschung (GSI), by a group headed by Peter Armbruster and Gottfried Münzenberg. They bombarded a target of bismuth with accelerated iron ions.

Properties of Roentgenium. The element has a metallic gold (yellow solid) appearance. The element has around 7 isotopes whose half-lives are known, with mass numbers from 272 to 282. One of the isotopes of this element (218 Rg) has a half-life of 26 seconds. The element undergoes decay under spontaneous fission process. Certain Facts About

Roentgenium is a chemical element with the symbol Rg and atomic number 111. 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, although the unconfirmed roentgenium-286 may have a longer half-life of about 10.7 minutes.
