Promethium Electrons per Shell (Pm) [& Color, Discovery ... 2022

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

In the case of Promethium the number of electons per shell is 2,8,18,23,8,2. Besides the distribution of electrons there is a lot of funny facts about Promethium that most don't know. Let me show you...
