Elements are currently unnamed, highly radioactive
Two new elements are to appear on the periodic table after a three-year review by the International Union of Pure and Applied Chemistry, and the International Union of Pure and Applied Physics, the governing bodies of both disciplines. The elements are unnamed as of yet, the BBC reports, but they’re both extremely radioactive and exist for less than a second before decaying into lighter atoms. Several labs have claimed to have discovered new chemical elements, but these two are the only one to fulfill criteria for now. They’ve been temporarily named ununquadium and ununhexium.
