Oxidation number of Ozone

Postby Qiu Ya Wu 4I » Wed Feb 19, 2020 11:37 pm

Is the overall oxidation number for ozone 0? How could this occur if the oxygen atom is commonly regarded to have an oxidation number of -2?

The oxidation number is 0 for ozone since it is a form of elemental oxygen the same applies for O3 as for O2.

It is 0 because no electrons are transferred.

Yes, O3/ozone has an oxidation number of zero, its formal charge is zero as well.

How do you find oxidation numbers?

Group one would be +1, group two would be +2, group seventeen would be -1. Neutral compounds would have a total oxidation number of 0, so you can usually figure out individual oxidation numbers of atoms from knowing one atom out of the compound (E.g. CrCl3, Cl has a -1 oxidation state, so Cr would be +3).

In compounds with only one element the oxidation number is 0

Oxidation numbers of many elements are not fixed. Here is a site with more information about some rules that one must follow when assigning oxidation numbers: https://www.thoughtco.com/rules-for-assigning-oxidation-numbers-607567.

If you look at the lewis structure of ozone, it does have individual oxygen formal charges but the overall formal charge is 0 and there is resonance; the oxidation number of the whole molecule of ozone (not of the individual oxygen atoms that compose it) is thus 0.

Oxidation number would be 0 as the overall charge of O3 is 0.

this is in an elemental state so it should be 0
