Nihonium, Moscovium, Tenness and Oganesson - these are the names of the four youngest members of the periodic table. More precisely: No. 113: Nihonium (Nh), No. 115: Moscovium (Mc), No. 117: Tenness (Ts), and No. 118: Oganesson (Og). The existence of elements 114 and 116 (Flerovium and Livermorium) would be recognized as early as 2011.

How are such elements actually produced and how can they be detected if they exist for a maximum of a few seconds? What do we know about their properties so far? And is Organessum perhaps not a noble gas at all, like the other representatives of Group 18, but a solid? In his contribution to "Chemie in unserer Zeit", Klaus Roth takes us on an exciting journey into the basic research of the very heavy elements.

Here is a video on Tennessine published by the Oak Ridge National Laboratory in Tennessee, USA.
