Facts about the Definition of the Element Roentgenium
The Element Roentgenium is defined as...
Roentgenium is a chemical element in the periodic table that has the symbol Rg (formerly temporarily Uuu) and atomic number 111. It has an atomic weight of 272 making it one of the super-heavy atoms. It is a synthetic element whose only known isotope has a half-life of around 15 ms before it decays into meitnerium. Due to its presence in Group 11 it is a transition metal and so probably metallic and solid.

Facts and Info about the element Roentgenium - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 which includes the Roentgenium element. The famous Russian Scientist, Dimitri Mendeleev, perceived the correct classification method of "the periodic table" for the 65 elements which were known in his time. Roentgenium was discovered by S. Hofmann at the Gesellschaft fur Schwerionenforschung in Darmstadt, Germany in 1994. The Standardised Periodic Table now recognises more periods and elements than Dimitri Mendeleev knew in his day but still all fitting into his concept of the "Periodic Table" in which Roentgenium is just one element that can be found.
