2022: ☢️ Electron Configuration of Astatine (At) [Complete, Abbreviated, Uses ...

Electrons have a specific form of distribution (or configuration) in every atom, even Astatine. Some are hard to memorise (or predict), so what is the electron configuration of an atom of At?

In the case of Astatine the abbreviated electron configuration is  [Xe] 4f14 5d10 6s2 6p5. Nevertheless, check the complete configuration and other interesting facts about Astatine that most people don't know.
