Flerovium is the superheavy artificial chemical element with the symbol Fl and atomic number 114. It is an extremely radioactive element that can only be created in the laboratory and does not occur in nature. The element is named after the Flerov Laboratory of Nuclear Reactions of the Joint Institute for Nuclear Research in Dubna, Russia, where the element was discovered in 1998. The name of the laboratory, in turn, honors the Russian physicist Georgy Flyorov. The name was adopted by IUPAC on May 30, 2012.Symbol: Uuq
