The periodic table isn’t what it used to be. Four new man-made elements have been verified by the International Union of Pure and Applied Chemistry (IUPAC) and added to the famous grid. Elements 113, 115, 117 and 118 are yet to be officially named -- that's a process that will take a few months -- but we’ve been given temporary working names and symbols. These are as follows.
- Element 113: Ununtrium, Uut
- Element 115: Ununpentium, Uup
- Element 117: Ununseptium, Uus
- Element 118: Ununoctium, Uuo
This is the first time the periodic table has changed since 2011, and neat freaks will be thrilled that the seventh row has now been completed. A team from the Joint Institute for Nuclear Research in Dubna and Lawrence Livermore National Laboratory in California has been credited with finding Elements 115, 117, and 118, while a separate group of scientists from the Riken Institute in Japan has been given the plaudits for discovering element 113.
They're going to have to update the periodic table song again. [Verge]
