What is the oxidation number for element O?

The oxidation number of O in any elemental form (e.g. O2, O3) is zero. Typically in chemical compounds the oxidation number of O is -2 (oxide ion)


Does Oxygen have the same oxidation number in ozone O3 and in oxygen O2?

No, the oxidation number of oxygen in ozone (O3) is -2/3, while in oxygen (O2) it is 0. In ozone, one oxygen atom has an oxidation number of -1 and the other two have an oxidation number of 0, resulting in an average oxidation number of -2/3.


What is the oxidation number of Mn2 O3?

O.S. of Mn = +3 O.S. of O = -2 O.N. of cpd = 0


What is the oxidation number of O3?

THe oxidation number for 'O3' is zero(0). O3 is ozone, and each oxygen atoms forms two single bonds with each of the other oxygens, forming a triangular arrangement.


What is the proper assignment of oxidation numbers to the element in the compound CsAs O3 would be?

In CsAsO3, cesium (Cs) is in Group 1A, which has an oxidation number of +1. Oxygen (O) typically has an oxidation number of -2. Since the compound is neutral, the oxidation number of arsenic (As) can be calculated using the sum of the oxidation numbers in the compound, which is +5 for As in this case.


What is the oxidation number of ozone?

Though it is very reactive, the oxidation number of ozone (O3) is zero: it is the tri-atomic form of elemental oxygen. The same applies to the di-atomic O2 molecule.


What is the oxidation number of H2SO3?

H is +1, O3 is -6, that is -5 -5 and the total charge is -1 so a -4 has to be contributed by S


What is the oxidation number of H2O2?

The oxidation number for H is +1, and the oxidation number for O is -1.


What is the oxidation number of Si in the Si O3-2?

+4 for silicon, -2 for each oxygen


What is oxidation number of N2O5?

In N2O5, the oxidation number of N (nitrogen) is +5 and the oxidation number of O (oxygen) is -2.


What are the oxidation numbers for each atom involved in the reaction 4ko2 and 2co2-2k2co3 and 3co2?

In KO2, O has an oxidation number of -1, K has an oxidation number of +1. In CO2, O has an oxidation number of -2, C has an oxidation number of +4. In K2CO3, O has an oxidation number of -2, C has an oxidation number of +4, and K has an oxidation number of +1. In the given reaction, the oxidation numbers for each atom remain the same as in their individual compounds.
