Element 118In 2006, the creation of the heaviest man-made element was announced by researchers from Russia's Joint Institute of Nuclear Research and the U.S. Lawrence Livermore National Laboratory. The results were published in the journal Physics Review C. The element, if confirmed, is the first man-made noble gas, below radon on the periodic table. The new element resulted from the collision of accelerated calcium ions with atoms of the man-made heavy element californium, and existed barely a millisecond before decaying into element 114, then element 112 and then split in half. A claim in 1999 for element 118 from kryton and lead was retracted in 2001 after independent confirmation failed. The new work was closely scrutinized.« |
