Livermorium and Flerovium take a seat at the Periodic Table
Just when we thought those pesky scientists had stopped messing with the Periodic Table, the International Union of Pure and Applied Chemistry goes and ratifies another two. The pair of elements were discovered in partnership between the Flerov Laboratory of Nuclear Reactions, Joint Institute for Nuclear Research in Russia and the Lawrence Livermore National Laboratory in the States. Element 114 has taken on the spell-check-worrying nomenclature Flerovium (Fl), while 116 becomes Livermorium (Lv). Eagle-eyed readers will notice that both take a name from the labs where they were discovered, the former named after Georgiy N. Flerov and the latter after Ernest O. Lawrence -- both atomic pioneers in their respective countries. The official names will get their first official publication in July's edition of Pure and Applied Chemistry. We guess those textbook makers will be rubbing their hands in glee at all those revised editions it'll sell next term. [Image courtesy of the BBC / Talkback Thames]
Periodic Table welcomes two new, ultraheavy elements, jury still out on the names
If you bump in to the Periodic Table of Elements today, be sure to give it a hearty Mazel Tov, because it's just welcomed two new members to the family. Yesterday, the International Union of Pure and Applied Chemistry (IUPAC) officially recognized elements 114 and 116, crediting the discovery to scientists from Russia's Joint Institute for Nuclear Research and the Lawrence Livermore National Laboratory, in California. Boasting atomic masses of 289 and 292, respectively, the new man-made additions are now the heaviest elements on record, seizing the belt from copernicium (285) and roentgenium (272). As with most heavyweights, however, both decay within less than a second, making it difficult for researchers to get a grasp of their chemical properties. Nevertheless, both apparently had enough credibility to survive IUPAC's three-year review process, paving the way for the real fun to begin. At the moment, 114 and 116 are known, rather coldly, as ununquadium and ununhexium, respectively, though their names will eventually be jazzed up -- sort of. The Russian team has already proposed flerovium for 114 (after Soviet nuclear physicist Georgy Flyorov), and, for 116, the Moscow-inspired moscovium, which sounds more like an after shave for particularly macho chemists. IUPAC will have the final say on the matter, though one committee member said any proposed names are likely to be approved, as long as "it's not something too weird." Head past the break for a full, and somewhat obtuse PR.
