Valency (according to the classical concept):Different elements combine together to give millions of compounds. Subsequently, question is, why the Valency of so4 is 2? Atom contains less than four electrons in its outermost shell; the valency of an atom is equal to the number of electrons present in the valence shell. But it is easier for sulphur to gain two electrons instead of losing six electrons.Hence, its valency is determined by subtracting six electrons from the octet and this gives a valency of two for sulphur.
