Chemical element 111 named 'roentgenium

 

08.11.2004

Since November 1, 2004, the chemical element with the atomic number 111 has an official name. Following a proposal of GSI, where the element was discovered, it will be named 'roentgenium' with the symbol 'Rg'. This proposal had been accepted by the International Union of Pure and Applied Chemistry IUPAC in its meeting in Bled, Slovenia, and was disclosed to the public today. Thus, roentgenium is the heaviest named element on the periodic table of the elements.
