The last step of this method involves adding the half reactions together to get our overall balanced equation,  and check to see if any reactants and products appear on both sides. We can balance the charges by including the electrons (which have negative charge) being transferred, and then we will get our reduction half-reaction right and balanced: now, if we add up the charges, including the electrons that have been transferred,  we end up with an overall charge of 0 at both sides of the reductions half-reaction. This makes it easier to follow any transfer of electrons. First, let’s learn the basic rules of finding the oxidation number: 1.
