Sodium ion has a valency or charge of 1+ where is oxide Ion has a valency or charge of 2-Na O 1+ 2- (cross over valencies) Formula: Na2O Hence, the formula of sodium oxide is Na2O. So we have to look at the number of electrons on its outermost shell. oxygen has a valency of 2.thus,three atoms of oxygen should contribute to a valency of 6.This is the valency of 2 M atoms in M2O3,thus,each M atom has a valency of 3.Sulfate is SO4(2-),thus it has a valency of 2 too,similar to oxygen.Using the same explanation,we deduce that the sulphate has a formula M2(SO4)3 Let’s understand the valency by following examples – 1. Valency is defined as number of electrons present in valence shell which are being lost, gained or shared with other atoms to form molecules and gain stability. The valency of an element is combining the capacity of an element which is measured in terms of the number of the hydrogen atom or its equivalent that combine to one atom of an element.
