Scientists from Russia, US and Japan complete periodic table's seventh row with four new elements

55   The new periodic table as of May 2013International Union of Pure and Applied ChemistryScience textbooks around the world will be ready for an overhaul as the periodic table now has its seventh row completed with the introduction of four new elements. The elements 113, 115, 117 and 118, discovered by scientists in Japan, Russia and America are the first to be added to the table since 2011, when elements 114 and 116 were added.The four elements which are not to be found in natural form as they are synthetic elements and can only be produced in the lab, were approved by the International Union of Pure and Applied Chemistry (IUPAC), the global organisation that governs chemical nomenclature, terminology and measurement on 30 December.

The chemistry community is eager to see its most cherished table finally being completed down to the seventh row," said Professor Jan Reedijk, president of the Inorganic Chemistry Division of IUPAC.The IUPAC has now invited the scientists who discovered the elements to propose permanent names and symbols as they are only temporarily recognised as



Ununtrium, (Uut) - Element 113
Ununpentium (Uup) - Element 115
Ununseptium (Uus) - Element 116
Ununoctium (Uuo) - Element 117
While elements 115, 116 and 117
have been credited to a team of Russian-American scientists at the Joint Institute for Nuclear Research in Dubna and Lawrence Livermore National Laboratory in California, element 113 has been credited to Japanese scientists from the Riken institute in Japan. Element 113 will in fact be the first element to be named in Asia.
