4 New Superheavy Elements Land on Periodic Table

Four new elements will join more than a hundred others on the periodic table of the elements, the International Union of Pure and Applied Chemistry (IUPAC) announced last week. IUPAC has now initiated the process of formalizing names and symbols for these elements," Jan Reedijk, president of the Inorganic Chemistry Division of IUPAC, said in a statement. Right now, the new elements have placeholder names and symbols that denote the elements' atomic numbers.
