Electron Configuration of Protactinium (Pa) [Complete, Abbreviated, Uses ... 2022

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

In the case of Protactinium the abbreviated electron configuration is  [Rn] 5f2 6d1 7s2. Nevertheless, check the complete configuration and other interesting facts about Protactinium that most people don't know.
