Scientists from the scientific governing committees of physics and chemistry have added two new elements -- yet to be named -- to the periodic table, reports The Associated Press (AP). The elements, currently known only as 114 and 116, are both highly radioactive and, with respective atomic weights of 289 and 292, are now the heaviest elements on the periodic table of elements, bumping copernicium and roentgenium down the list of heavyweights. The two radioactive elements exist only for a...
