In recognition of a great contribution to heavy elements synthesis, Armenia portrayed Yuri Ts. Oganessian on a postage stamp on 28 December 2017. The symbol of element 118 of the Periodic Table named after this brilliant physicist is also depicted on the stamp. There are 40000 stamp copies.

Yuri Ts. Oganessian greatly contributed to research of transactinide elements. His many achievements include the discovery of superheavy elements and significant advances in the nuclear physics of superheavy nuclei including experimental evidence for the “island of stability”. For the element with atomic number 118 the collaborating teams of discoverers at the Joint Institute for Nuclear Research, Dubna (Russia) and Lawrence Livermore National Laboratory (USA) proposed the name oganesson and symbol Og. The proposal is in line with the tradition of honoring a scientist and recognizes Professor Yuri Oganessian for his pioneering contributions to transactinoid elements research. Thus, on 30 November 2016, the International Union of Theoretical and Applied Chemistry (IUPAC) confirmed the name “oganesson” for element 118.
