Lanthanum Electrons per Shell (La) [& Color, Discovery ...

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

In the case of Lanthanum the number of electons per shell is 2,8,18,18,9,2. Besides the distribution of electrons there is a lot of funny facts about Lanthanum that most don't know. Let me show you...

Lanthanum Overview
