Facts and Info about the element Radon - 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 Radon 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. Radon was discovered by Friedrich Ernst Dorn in 1900. William Ramsay and Robert Whytlaw-Gray isolated it and gave it the name 'Niton' in 1908. 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 Radon is just one element that can be found.
