118's ELement ( Oganesson)

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 the member of the noble gas group.
The element no. 118 on the periodic table of elements, had previously been designated Unuoctium, a placeholder name that means one-one-eight in Latin. In November 2016, IUPAC approve the name Oganesson for the element 118.
Oganesson was discovered in 2002 by Russian scientist at the Joint institute for Nuclear Research in Dubna, Russia. Three years prior, 1999, the team at Lawrence Berkeley labs in California published a paper announcing the discovery of element 118, but their results could not be replicated and the team retracted their paper. In 2006, the element was officially announced by Dubna team and by Lawrence National laboratory team.
