| Found in | Work cat.: Aldridge, S. Ununquadium, ununtrium, ununpentium, ununhexium, ununseptium, and ununoctium, 2012. Beck, J. Two new super-heavy elements added to the periodic table, 2011, via Popsci website, viewed Aug. 31, 2012 (The periodic table of the elements now officially has two new members, its heaviest ever. The new elements, 114 and 116 weigh 289 and 292 atomic mass units, respectively. Elements 114 and 116 currently have placeholder names - ununquadium and ununhexium. Their Russian discoverers at Dubna Joint Institute for Nuclear Research have proposed to name 114 flerovium for Soviet nuclear physicist Georgy Flyorov and to name 116 moscovium after the region Moscow Oblast.) Mann, A. 2 new elements named on periodic table, 2012, via Wired science website, viewed Aug. 31, 2012 (two new residents of the period table of elements: Flerovium and Livermorium; The International Union of Pure and Applied Chemistry officially approved names for the elements - which sit at slot 114 and 116, respectively - on May 31. They have until now gone by the temporary monikers ununquadium and ununhexium. Both elements are man-made, having first been synthesized at the Joint Institute of Nuclear Research in Dubna, Russia, in 1998 and 2000; Flerovium's symbol will be Fl (not to be confused with fluorine)) Wikipedia, Aug. 31, 2012 (Flerovium (formerly ununquadium) is the radioactive chemical element with the symbol Fl (formerly Uuq) and atomic number 114. The element is named after Russian physicist Georgy Flyorov, the founder of the Joint Institute for Nuclear Research in Dubna, Russia, where the element was discovered. The name was adopted by IUPAC on May 31, 2012. Element category: unknown; likely a post-transition metal, although possibly chemically inert like a noble gas) Maugh, T.H. Livermorium and flerovium : new names for heavy elements, via Los Angeles times, June 1, 2012, viewed on Aug. 31, 2012 (The super-heavy elements 114 and 116 have officially been recognized by the International Union of Pure and Applied Chemistry, the official arbiter of chemical names, and have been named in honor of the U.S. and Russian institutions where they were jointly discovered. Element 114 has been named flerovium, with the symbol Fl, in honor of the Flerov Laboratory on Nuclear Reactions in Dubna.) The element flerovium, via It's elemental : the periodic table of elements website, Aug. 31, 2012 (Flerovium; Fl; Atomic Number: 114; Atomic Weight: 289; Element Classification: Metal; Period Number: 7; Group Number: 14; Group Name: none; radioactive and artificially produced; Flerovium was first produced by scientists working at the Joint Institute for Nuclear Research in Dubna, Russia in 1998. They bombarded atoms of plutonium with ions of calcium. This produced a single atom of flerovium-289, an isotope with a half-life of about 21 seconds. Flerovium's most stable isotope, flerovium-289, has a half-life of about 21 seconds. It decays into copernicium-285 through alpha decay.) |
