Possible oxidation states are +2,4. Based on the activity series, all of those metals should be able to displace Pb2+ in a single displacement reaction.Maybe it just has to do with the fact that FeCl2 and MgCl2 are valid formula but NaCl2 and KCl2 are not (rather the equation would be PbCl2 + 2Na --> Pb + 2NaCl). Furthermore, why doesn't carbon also have a $2^{+}$ oxidation number, as can't it also give up its two electrons in the p-suborbital to have a full s-suborbital? oxidation number- the charge that appears on any atom of a molecule is known as its oxidation no. in this reaction oxidation number of Pb atoms of reactant is +4 while of product +2 so Pb should absorbed electrons.Oxidation number of O in reactant is -2 while in product 0 so O should release electrons .
