Oganesson is the element with atomic number 118. Very little is known about this element. It is classified as a non-metal and is expected to be a gas.
The International Union of Pure and Applied Chemistry (IUPAC) approved the name oganesson for element 118 in November 2016. This name honours Yuri Oganessian, a famous scientist.
This element was discovered by a team of Russian scientists at the Joint Institute for Nuclear Research in Dubna, Russia in the year 2002. A team at the Lawrence Berkeley Labs in California published a paper in 1999 announcing the discovery of element 118. But their results could not be repeated and the team took back their paper.
Later, in 2006, the element was officially announced by the researchers at Dubna and by the team at the Lawrence Livermore National Laboratory, who were working with the Dubna scientists.
