Four new elements have been added to the periodic table, making science textbooks across the world out of date.
The elements were verified and added by the International Union of Pure and Applied Chemistry (IUPAC) last week, making the scientific chart’s seventh row officially complete.
The inclusion of the super-heavy man-made chemical elements temporarily named 113, 115, 117 and 118 are the first additions to the table since 2011.
Element 113 was discovered by the RIKEN institute in Japan. It’s working name is ununtrium and symbol is Uut.
Elements 115 and 117 were discovered by scientists from the Joint Institute for Nuclear Research in Dubna, Russia, the Lawrence Livermore National Laboratory in Livermore, California and the Oak Ridge National Laboratory in Oak Ridge, Tennessee. Their working names and symbols are ununpentium and Uup for 115, and ununseptium and Uus for 117.
Element 118 was discovered by the teams from Dubna and California, and is currently named ununoctium, with the symbol Uuo.
