WebSep 13, 2024 · Such as iron. It has two valences, two and three. Iron will lose two electrons at some point and turn into rt and at another time it will lose three electrons and turn into py. There are also many elements that have more than one valence. Problem6 How many valence electrons does oxygen have? The valence electron of oxygen will be 6. WebJan 23, 2024 · The charged carbon atom in a carbocation is a "sextet", i.e. it has only six electrons in its outer valence shell instead of the eight valence electrons that ensures maximum stability (octet rule). Therefore, carbocations are often reactive, seeking to fill the octet of valence electrons as well as regain a neutral charge.
