“Four new elements have been added to the periodic table, finally rounding out the chemical table’s seventh row,” reported Time.com
Elements 113, 115, 117, 118 have been added to the periodic table that have been recognized by the International Union of Pure and Applied Chemistry (IUPAC), the U.S.-based world authority on chemistry on December 30th, 2015.
“The Joint Institute for Nuclear Research in Russia, Lawrence Livermore National Laboratory in California, and Oak Ridge National Laboratory in Tennessee were credited with enough evidence to discover elements 115, 117 and 118,” commented CNN.com
“The chemistry community is eager to see its most cherished table finally being completed down to the seventh row. IUPAC has now initiated the process of formalizing names and symbols for these elements temporarily named as ununtrium, (Uut or element 113), ununpentium (Uup, element 115), ununseptium (Uus, element 117), and ununoctium (Uuo, element 118)” reported Sciencemag.org.
