Let's take into account the number of atoms of each element we have and make an equation since we know everything has to add up to zero since the molecules is neutral. From our rules we know that O= -2 and we can find K on the periodic table, in the first group, thus giving it a +1 charge. +1 +x+3(-2) =0 (notice we multiplied 3 by -2, because in the formula we have 3 atoms of oxygen with -2 charge each), Therefore, the oxidation number of N in KNO3 is +5. The oxidation number for NO3, or nitrate, is -1. The oxidation number is a positive or negative number that is assigned to an atom to indicate its degree of oxidation or reduction. The three oxygen atoms have a combined oxidation of -6, corresponding to their electromagnetic charge and the lone nitrogen has a charge, or oxidation number, of +5. K=+1 N=x O=-2. We have a H-Cl molecule; when we break the bond (conceptually!)
