oganesson

English

Chemical element
Og
Previous: tennessine (Ts)
Next: ununennium (Uue)

Etymology

Oganessian +‎ -on. Promulgated in June 2016 by the IUPAC based on recommendations of the Joint Institute for Nuclear Research and Lawrence Livermore National Laboratory to honor the Russian-Armenian physicist Yuri Oganessian (born 1933) who researched superheavy elements. Suffix -on, rather than -ium, is due to it being a noble gas (like neon or argon).

Pronunciation

enPR: ōgənĕs'ŏn, IPA^(key): /oʊ.ɡəˈnɛsɒn/

Noun

oganesson (uncountable)

The chemical element (Symbol Og) with atomic number 118. It is the heaviest known element. Highly radioactive, it does not occur naturally. Originally expected to be a noble gas, it is now predicted to be a reactive metallic solid, and a semiconductor or a post-transition metal. [1]
- 2016 June 9, “Meet the periodic table's 4 new elements: Nihonium, moscouvium, tennessine and oganesson”, in The Straits Times‎:
  SINGAPORE - The four new elements announced in December last year have received their new names: Nihonium (Nh), moscouvium (Mc), tennessine (Ts) and oganesson (Og).
- 2018, Mark Weller; Tina Overton; ‎Fraser Armstrong; Jonathan Rourke, chapter 1, in Inorganic Chemistry‎, Oxford University Press, →ISBN, page 21:
  In January 2016 the International Union of Pure and Applied Chemistry (IUPAC) announced the discovery of four new elements, so completing the seventh row of the periodic table. They have since been named as nihonium, Nh, muscovium^[sic], Mc, tennessine, Ts, and organesson^[sic], Og. The procedures for naming new elements are clearly laid out by IUPAC.
- 2019 February 27, Emily Conover, “Extreme elements push the boundaries of the periodic table”, in Science News‎:
  Researchers carefully choose the makeup of the beam and the target in hopes of producing a designer atom of the element desired. That’s how the four newest elements were created: nihonium (element 113), moscovium (115), tennessine (117) and oganesson (118) (SN Online: 11/30/16).
