If newer elements don’t fall in line with the properties we might predict from the periodic table, then it loses its predictive power for these and subsequent elements.Īt present, some might see this as something of an irrelevance. In the past, chemists were able to use the properties of elements they knew to predict the properties of the elements they’d yet to discover, based on their position in the periodic table. Part of the genius of its design is the way in which elements with similar chemical properties are grouped together. This has resounding implications for the periodic table. However, calculations suggest it should be a metallic semiconductor, making its properties distinctly different from the other elements in its group. It’s a member of the noble gas group of elements, which should mean it’s (as the name suggests) a gas at room temperature, and fairly unreactive. Though scientists are working to try and make heavier elements, so far they’ve yet to succeed.Īnother of oganesson’s distinctions is that it’s one of the periodic table’s weirdest elements – based on predicted properties, at least. Secondly, it’s currently the heaviest element we’ve managed to make. It’s named after Yuri Oganessian, the Russian-Armenian physicist who’s considered to be the leading researcher in the world when it comes to making superheavy elements. Firstly, it’s the only element named after someone who’s still alive. Oganesson has several distinctions amongst all of the elements in the periodic table. Oganesson was discovered in 2002 and its properties defy our expectations based on trends in the periodic table. Element 118, the final element in our International Year of the Periodic Table series, is oganesson.
