Electrons that are found in the outermost shell are generally known as valence electrons and the number of valence electrons determines the valency (or valence) of an atom. The number of electrons in an atom that actually take part in bond formation is known as valency and the electron which are present in the outermost shell is known as valence electron. all gases at room temperature. So, valency cannot be related to charge. Get to know everything about the Manganese valence electrons here in the article.
