2022: ☢️ Valence Electrons in Erbium (Er) [& Facts, Color, Discovery ...

A valence electron is an outer shell electron and may participate in the formation of a chemical bond. Ok but how many valence electrons does an atom of Erbium have?

In the case of Erbium the valence electrons is 3. Now let's check the facts about Erbium...
