How is the valence of an element determined?

Oxidation State and valency are one of the most fundamental properties of elements and can be studied with the help of electron configurations. 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.
