The element should be the most electropositive of the noble gases, and, therefore, the existence of a (partially ionized) difluoride of oganesson is predicted. They decided to call it oganesson to honor Oganessian because, without him, there wouldn’t be any further research on superheavy chemical elements that can be naturally or synthetically produced on Earth. Before the official discovery of oganesson in 2015, there have been many scientists claiming to be the first to discover the element. After a year, the second test researchers stated that they had found three nuclei of the isotope oganesson-204 that is produced through the collision of calcium-48 ions and californium-249 atoms. In 2011, the International Union of Pure and Applied Chemistry or IUPAC reviewed the findings in 2006, and they concluded that the study was not enough to support the claim that the new element has already been discovered. Before the discovery of oganesson, many chemists have already speculated that there is a seventh noble gas after neon, argon, helium, krypton, xenon, and radon, and this speculation has already been stated right after the first noble gas was discovered.
