Inorganic Chemistry Division

Name and Symbol of the Element with Atomic Number 111

Prepared for publication by J. Corish and G. M. Rosenblatt

A joint IUPAC-IUPAP Working Party (JWP) has confirmed the discovery of element number 111 and this by the collaboration of Hofmann et al. from the Gesellschaft für Schwerionenforschung mbH (GSI) in Darmstadt, Germany. In accord with IUPAC procedures, the discoverers have proposed a name and symbol for the element. The Inorganic Chemistry Division Committee now recommends this proposal for acceptance. The proposed name is roentgenium with symbol Rg.

This proposal lies within the long established tradition of naming elements to honour famous scientists. Wilhelm Conrad Roentgen discovered X-rays in 1895.
