In the periodic table, tennessine is expected to be a member of group 17, the halogens. [c] Some of its properties may differ significantly from those of the lighter halogens due to relativistic effects. As a result, tennessine is expected to be a volatile metal that neither forms anions nor achieves high oxidation states.
