The possibility of a seventh noble gas, after helium, neon, argon, krypton, xenon, and radon, was considered almost as soon as the noble gas group was discovered.
oganesson (Og), a transuranium element that occupies position 118 in the periodic table and is one of the noble gases. Oganesson is a synthetic element, and in 1999 scientists at Lawrence Berkeley National Laboratory in Berkeley, California, announced the production of atoms of oganesson as a result of the bombardment of lead -208 with atoms of ...
It’s possible oganesson forms a diatomic gas (Og 2). Oganesson likely acts as a semiconductor. The lighter noble gases are all insulators. Oganesson may form an ionic bond with fluorine. In contrast, other noble gases form covalent bonds with fluorine (if they form any bonds at all).
Oganesson (Og) is the last entry into the Periodic Table completing the seventh period of elements and group 18 of the noble gases. Only five atoms of Og have been successfully produced in nuclear collision experiments, with an estimate half-life for Og of 0.
IUPAC uses the term "noble gas" interchangeably with "group 18" and thus includes oganesson; however, due to relativistic effects, oganesson is predicted to be a solid under standard conditions and reactive enough not to qualify functionally as "noble".

Oganesson is a radioactive, artificially produced element about which little is known. It is expected to be a gas and is classified as a non-metal. It is a member of the noble gas group.
First synthesized in 2002 at the Joint Institute for Nuclear Research in Russia, oganesson is the only element of group 18 of the periodic table (noble gases), which doesn't naturally occur and must be synthesized in experiments.
As a noble gas, you would expect oganesson to have closed valence shells, ending with a filled 7 s2 7 p6 configuration. But in 2017, a US–New Zealand collaboration predicted that isn’t the...
Oganesson is the 118th element in the periodic table and has a symbol of Og and atomic number of 118. It has an atomic weight of (294) and a mass number of 293. Oganesson has one hundred eighteen protons and one hundred seventy-five neutrons in its nucleus, and one hundred eighteen electrons in seven shells.
