This may be a detail for you, but until last January, the periodic table of chemical elements were holes. It was without counting on the discovery of four elements missing from then officially complete the 7th line of the famous classification Mendeleev (see inset).

The first item highlighted in Japan even in Asia A real earthquake in the world of chemistry caused by Japanese, American and Russian, and then validated by the international Union of pure and applied chemistry (IUPAC).

it remained so to name these newcomers. And Japanese discoverers of the new entry 113 of the periodic table of chemical elements proposed on Thursday to appoint this element, “Nihonium” (Nh, in reference to the word “Nihon” , Japan). The element 113 is the first demonstrated in Japan and even in Asia.

“The elements 119 and 120 unknown” the Russian and American fathers chose the number 115 “Moscovium” or “Moscow” . The other two, also discovered by laboratory Russia and the United States, should be called “Tenessine” for the 117 (in thanks to research institutions in the State of Tennessee, Ts ) and “Oganesson” for the 118 (Og in reference to Professor Yuri Oganesyan).

as a reminder, the existence of Nihonium was shown three times between 2004 2012 Kosuke Morita, Professor of the University of Kyushu (southwest) and figure Riken research institute of the public. The latter immediately expressed Thursday its “ambition to also discover the 119 and 120 unknown elements” .

The periodic table of elements, also called table Mendeleev (named after the Russian scientist who created the first version in 1869) brings together the chemical elements classified according to their composition and chemical properties. In other words, all the chemical elements constituting the matter of the universe.
