The element with the highest atomic number is Oganesson (Og), which has an atomic number of 118. It was officially recognized as a chemical element in 2016 and is a synthetic element that does not occur naturally. Oganesson is part of the noble gas group, though its properties are predicted to differ from the other noble gases due to relativistic effects. Its name honors Russian physicist Yuri Oganessian for his contributions to the discovery of super-heavy elements. Due to its instability and short half-life, Oganesson has no commercial uses and is primarily of interest for research in nuclear physics.
