Element Officially Named After Armenian Physicist


RESEARCH TRIANGLE PARK, N.C. (A.W.)—On Nov. 28, the International Union of Pure and Applied Chemistry (IUPAC) approved the name and symbols for the four following elements: Nihonium (Nh), Moscovium (Mc), Tennessine (Ts), and Oganesson (Og)—after Russian-Armenian physicist Yuri Tsolakovich Oganessian.

The IUPAC holds a tradition of honoring a scientist and for element Og, the collaborating teams of discoverers at the Joint Institute for Nuclear Research, Dubna (Russia) and Lawrence Livermore National Laboratory (USA) proposed to recognize  Oganessian for his extraordinary contribution to transactinoid elements research.

On April 9, 2010, Oganessian and his team of Russian and American physicists published a paper discussing their discovery of element number 117 in “Physical Review Letters.”

The team led by Oganessian of the Joint Institute for Nuclear Research in Dubna, Russia, discovered the still unnamed element by colliding together calcium-48 (an isotope made of 20 protons and 28 neutrons) with berkelium-249 (which has 97 protons and 152 neutrons). The result of the fusion reactions was the creation of two isotopes—293117 and 294117—of an element with 117 protons. One isotope had 176 neutrons, and the other had 177. “After experiment on the synthesis [of] element 118, this is the second time when we [were able to produce] atomic nuclei with mass number 294,” Oganessian told the Armenian Weekly in 2010.

Some of his many achievements include his discovery of superheavy elements and contributing to the advances in the nuclear physics of superheavy nuclei.

In 2010, the Weekly asked Oganessian if he has any advice for the Armenian youth going into the scientific field. “I would wish to say [to] my young colleagues that scientific work is a hard labor,” said Oganessian.  “Once you have chosen this way, let you be not depressed by the problem of eternal search, let you be not saddened by setbacks, and let you never lose self-confidence. Some time or other, the fruits of your effort will be called for and your name will be referred to with gratitude by your successors.”
