Since is in column of the periodic table, it will share electrons and use an oxidation state of . P-doped MoS 2 also shows faster carrier transfer compared to pure MoS 2 owing to its low resistance. Relevance. To find the correct oxidation state of O in Na2O2 (Sodium peroxide), and each element in the molecule, we use a few rules and some simple math.First, since the Na2O2 molecule doesn’t have an overall charge (like NO3- or H3O+) we could say that the total of the oxidation numbers for Na2O2 will be zero since it is a neutral molecule.We write the oxidation number (O.N.) asked Feb 8 '17 at 16:11. To find the correct oxidation state of O in Na2O2 (Sodium peroxide), and each element in the molecule, we use a few rules and some simple math. +1,+1,-2 C.+1,+2,-2 D.-1,-2,-2 E.-1,-2,+3 I said E. But I'm think I'm wrong. The oxides formed. [C2O42−] = CRC Handbook of Chemistry and Physics. The oxidation number of oxygen is -2, so 7 O atoms times -2 = -14. Lv 7.
