Well, astatine is Group 17 in the halogen group.....


This is very rare element, with an electronic structure of #[Xe]4f^14 5d^(10)6s^2 6p^5#. The element thus has the same electronic structure as the higher halogens. Probably the material is too rare for chemists to investigate its reactivity definitively.
