Oganessonis the temporary name of a retractedchemical elementin theperiodic tablethat has the temporary symbol Og and has the atomic number 118. In1999, researchers atLawrence Berkeley National Laboratory宣布116年和118年发现的元素,我n a paper published inPhysical Review Letters. The following year, they published a retraction after other researchers were unable to duplicate the results. In June 2002, the director of the lab announced that the original claim of the discovery of these two elements had been based on data fabricated by principal author维克多Ninov. Oganesson would probably share the properties of its group, the noble gases, resemblingradonin its chemical properties. Health effects of OganessonOganesson doesn’t occur naturally, it has not been found in the earth’s crust, so there is no reason to consider its health hazards. Environmental effects of OganessonOganesson doesn’t occur naturally, it has not been found in the earth’s crust, so there is no reason to consider its environmental effects.
