The Friday File: If you love chemistry, there is now more to love. Until recently there were 114 elements, now there are 118! These new “superheavy” elements exist very briefly. Ununtrium (atomic number 113) exists for less than a thousandth of a second, much like my paycheck. The other elements have been give temporary names of ununpentium, ununseptium and ununoctium. These complete the seventh row of the periodic table.
