Roentgenium is a chemical element created in the laboratory with radioactive properties. Roentgenium has a half life of around 10.7 minutes. It is name after Wilhelm Rontgen, the discoverer of X rays. No chemical experiments have been conducted on the element but it is predicted to have similar properties to gold as it is in the same group. As so little of it has been created the melting and boiling point have not been analysed. It was discovered in Darmstadt, Germany, at the Institute for Heavy Ion Research in 1994.
