What is the electronic configuration of astatine?

Answer 1

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.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
