Oct 26, 2017 Yuri Tsolakovich Oganessian, a Russian nuclear physicist and leading researcher in superheavy elements, collaborated with ORNL scientists in the discovery of tennessine, an element with atomic number 117. According to RAS Academician Yuri Oganessian, the experiment on the synthesis of element 119 of the Periodic Table of Chemical Elements will start not earlier than the end of 2020 and will last for about 150 days. “The experiment will last not less than 150 days.

Four new element names proposed for periodic table

Yuri Oganessian helped to discover many super-heavy elements — and now one may be named after him.

The periodic table will soon have four new names added to its lower right-hand corner.

Element 113 should be named nihonium (Nh); element 115 moscovium (Mc); element 117 tennessine (Ts) and element 118 oganesson (Og), according to proposals outlined on 8 June by chemistry’s governing body, the International Union of Pure and Applied Chemistry (IUPAC).

The laboratories who were credited with the discovery of the elements – in Russia, the United States and Japan – got to propose the names under the constraint that elements can only be named after one of their chemical or physical properties, a mythological concept, a mineral, a place or country, or a scientist.Related stories

Is Oganesson A Noble Gas

“Although these choices may perhaps be viewed by some as slightly self-indulgent, the names are completely in accordance with IUPAC rules,” said Jan Reedijk, president of IUPAC's inorganic-chemistry division, in a media statement.

Perhaps the most striking choice, although one that was widely predicted, is for element 118, oganesson. It is named for Yuri Oganessian, an 83-year-old researcher at Russia’s Joint Institute for Nuclear Research (JINR) in Dubna who has helped to discover numerous superheavy elements, and will mark only the second time that an element has been named after a living scientist. The first such occasion led to huge controversy, when in 1993 a team at the Lawrence Berkeley National Laboratory proposed naming element 106 seaborgium for US nuclear-chemistry pioneer Glenn Seaborg. At the time an IUPAC committee rejected the proposal, after passing a resolution that elements not be named for living scientists, but it ultimately relented.

Moscovium (115) – named for the Moscow region – honours “the ancient Russian land that is home to the Joint Institute for Nuclear Research”, says IUPAC. And tennessine (117) 'is in recognition of the contribution of the Tennessee region, including Oak Ridge National Laboratory, Vanderbilt University, and the University of Tennessee at Knoxville, to superheavy element research,' IUPAC says. (A collaboration between the JINR, the Lawrence Livermore National Laboratory in Livermore, California, and the Oak Ridge laboratory, was credited with the discovery of these two elements).

Element 113, nihonium, is the first artificial element to be named in East Asia. When its creation was first claimed 12 years ago by a team at the RIKEN Nishina Center for Accelerator-based Science in Wako, near Tokyo, ‘japonium’ was suggested as a name. But the RIKEN group (who followed up with a more convincing report in 2012) chose nihonium instead; ‘nihon’ being one way to say ‘Japan’ in Japanese (日本). “The name is proposed to make a direct connection to the nation where the element was discovered,” an IUPAC press release explained.

The last new additions to the periodic table were flerovium (Fl, 114) and livermorium (Lv, 116). Like the latest four, all such artificial elements are created in trace amounts in the laboratory by smashing lighter atomic nuclei together – and last mere fractions of a second before they fall apart into smaller, more stable fragments.

IUPAC is allowing five months for public comment on the suggestions, but barring an upswell of public protest, these names will be confirmed in November.
