Astatine Electrons per Shell (At) [& Color, Discovery ... 2022

Atoms have electrons that need to be distributed somehow, even Astatine. Ok so where are these electrons in an atom of At?

In the case of Astatine the number of electons per shell is 2,8,18,32,18,7. Besides the distribution of electrons there is a lot of funny facts about Astatine that most don't know. Let me show you...
