The new elements of the periodic table are named – cnnespanol.com

(CNN) – Meet nihonio (NH), moscovio (Mc), tenesina (Ts) and oganesón (Og), the most recent elements of the periodic table. But do not get too attached to the nomenclature of these elements, previously known by their atomic numbers, respectively 113, 115, 117 and 118. The names are in a trial period of five months before things become official.

the elements were recognized by the International Union of Pure and Applied chemistry, or IUPAC, the world authority on chemical based in the US, December 30, 2015. Their addition completed the seventh row of the periodic table

.

discoverers of the elements were invited to propose names, and now a public review will occur until November 8, 2016. If you have strong feelings about the names, the union invites you to comment and comments.

the discoverers of the IUPAC provided guidelines to help them create names. These names follow the tradition of many years of being the name of a concept or mythological character (including the astronomical object), a mineral or a similar substance, place or geographic region, a property of the element or a scientist.

And, of course, must end in “onium” “ovio” or “on” depending on the grouping of elements belonging. Also it preferred IUPAC names that can be easily translated into several languages.

Other researchers are already working hard on finding items that can complete the eighth row, in addition to working to consolidate how the heavier elements are identified.

All four elements not found in nature, and are created in laboratories. So far, the elements have temporary names and symbols in the periodic table because it was difficult to prove their existence. Because decompose very rapidly, scientists found it difficult to play.

Element 113 was the first to be discovered in an Asian country. The researchers proposed the name nihonio to celebrate. “Nihon” is one of the two ways of saying “Japan” in Japanese, meaning “Land of the Rising Sun” The element was dscubierto by a team at the Nishina Center where a throttle led by Professor Kosuke Morita.

the researchers said their search for element 113 was initiated by “bombarding a thin layer of bismuth with zinc ions traveling at about 10% of the speed of light”. In doing so they formed the atom of element 113

A Russian-US team at the Joint Institute for Nuclear Research in Dubna, Russia, and the Oak Ridge National Laboratory in Tennessee and Lawrence Livermore National Laboratory in California he discovered elements 115, 117 and 118.

the moscovio and tenesina were discovered in Moscow and Tennessee, respectively. The researchers used a gas and heavy ion accelerator in the Flerov Laboratory of Nuclear Reactions in Moscow.

For tenesina researchers Oak Ridge National Laboratory, Vanderbilt University and the University of Tennessee in Knoxville worked together in investigating the element using isotopes of the high flux reactor at Oak Ridge and Development Center radiochemical Engineering.
