Confirm 4 new elements of the periodic table – lagranepoca

The elements 113, 115, 117, and 118 are called provisionally ununtrium, ununpentium, ununseptium and ununoctium, but already have official name: nihonio, moscovio, téneso and oganesón. / IUPAC

last June, the teams of chemists who had discovered elements 113, 115, 117 and 118 of the periodic table, applied to the International Union of Pure and Applied Chemistry (IUPAC) that are denominated –in English– nihonium, moscovium, tennessine and oganesson.

After the five-month period established for the allegations, this November 28, the IUPAC has officially approved the names of these four elements and their corresponding two letter abbreviations: Nh, Mc, Ts and Og. In Spanish would be nihonio, moscovio, téneso and oganesón.

For the choice of these names, and following the tradition of choose geographic terms or referred to scientists, it has been chosen to denote three elements in honor of Japan, Moscow, and Tennessee, and a fourth in homage to a Russian investigator.

The word nihonio, discovered by japanese researchers from the RIKEN Nishina Center for Accelerator-Based Science, means "the land of the rising sun". This is the first chemical element found and baptized from Asia. This team, led by professor Kosuke Morita, is confident that the finding also serves to recover the hope in the wake of the Fukushima nuclear disaster.

For its part, the moscovio and the téneso are joint proposals of its discoverers at the Institute for Nuclear Research in Dubna (Russia) and various centers of USA: Oak Ridge National Laboratory, Vanderbilt University in Tennessee and the Lawrence Livermore National Laboratory in California.

Finally, the name of the element oganesón underlines the work of the Russian physicist Yuri Oganessian (born in 1933). Among its many achievements include the discovery of elements superpesados and its experimental evidences of the so-called 'island of stability'.
