All the institutions that are related to the study of chemistry should update their tables because the same valences have already become outdated <. /> p>

Four new chemicals were added to the periodic table of valences in recent days. The provisional name of the new elements are: ‘ununtrium’ (‘Uut’ or element 113), ‘ununpentium’ (‘Uup’, element 115), ‘ununseptium’ (‘Uus’, element 117), and ‘ununoctium’ (‘Uuo’, element 118) “.

According to information provided by the International Union of Pure and Applied Chemistry (IUPAC, for its acronym in English) to The Guardian, these substances have been discovered scientists from Japan, Russia and the United States. They are the first to be added to the table from which the elements were added 114 and 116.

The four discoveries in 2011 were verified on 30 December by the Iupac, global organization that governs chemical nomenclature, terminology and measurement, based in the United States. According to The Guardian IUPAC announced that a Russian-American team of scientists from the Joint Institute for Nuclear Research in Dubna (Russia) and the Lawrence Livermore National Laboratory in California (USA), had provided sufficient evidence to claim the discovery of elements 115, 117 and 118. However, the Iupac granted credit for the discovery of element 113 to a computer Scientists at the Riken Institute in Japan, although it had also been claimed by the Russians and Americans.

The Japanese research director, Kosuke Morita, announced after the news that his team now plans to “look into the uncharted territory of element 119 and beyond.”

The items will be officially appointed by the teams who discover in the coming months, this nomination will depend on “parents” of scientific findings.

The four new elements, all made artificially, they were discovered by more light hitting each other and the consequent decay of radioactive nuclei superheavy elements.

Like other superheavy elements that populate the bottom of the periodic table, exist only for fractions of a second before decaying into other elements.
