Oganesson has a closed-shell electronic structure [Rn]5f146d107s27p66 and should therefore be regarded formally as the bottom-most member of the periodic group of inert gases. Oganesson. Relative atomic mass The mass of an atom relative to that of . While it's possibly a semiconducting noble gas, most scientists predict the element will be a liquid or solid at room temperature. 19 - 21 In order to resolve this long-standing controversy, we employ two complementary approaches to calculate the melting temperature of Og. Oganesson may, however, be a liquid at room temperature and pressure. Right: A similar transition to uniform-gas behavior in the valence region is also expected for the neutron localization of As an element, Oganesson fits in the group of the so-called "noble gases" but is predicted to be a solid at room temperature. element astatine. Bromine and iodine also exist as gases at room temperature and standard pressure though their main forms are not gas. ajbeck Oganesson is harmful due to its radioactivity. If the element is a gas, it would be the densest gaseous element, even if it is monatomic like the other gases in the group. In contrast to other noble gases, theories suggest that Oganesson would be liquid at room temperature, and it would have a boiling point of around 320 K - 380 K.
