Oxidation numbers are an invention of chemists; they are simply an accounting scheme that helps chemists to keep track of things in a redox reaction.
There are several different ways to assign oxidation numbers in ozone.
The only fixed point that all would agree on is that the sum of oxidation numbers on the three atoms must come to zero.
Argument 1: All 3 atoms are oxygen, so they all have the same electronegativity, so the oxidation numbers must be 0,0, and 0
Argument 2: When writing the formula of ozone and trying to obey the rules of valence, you have to use formal charge. The formula could be written
O=O(+)-O(-)
In this case the oxidation numbers must be assigned as 0,+1, and -1
Argument 3: The formulation of argument 2 is correct BUT both "end" oxygen atoms are in symmetrically identical environments, and the formula written above is just one of two resonance structures. The symmetry of the molecule must be recognised, and so the oxidation numbers are -1/2 , +1, and -1/2
You can find professional chemists who will argue quite strongly for any one of these three assignments. None of them is really "right" or "wrong". It is all a matter of how you want to do your accounting. (But just sit back and nod wisely if you find a chemist who is arguing passionately for a particular assignment).
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.
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.
The oxidation number of each carbon atom in C6H8O6 is +4. Each hydrogen atom has an oxidation number of +1, and each oxygen atom has an oxidation number of -2.
The oxidation number of each oxygen atom in peroxide is -1.
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
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.

The oxidation number of oxygen in K2O2 is -1. Each oxygen atom in peroxide (O2^2-) has an oxidation number of -1.
The oxidation state of Hydrogen in the hydronium ion is 1+ and the oxidation state of oxygen is 2-
The oxidation number of hydroxide (OH-) is -1. This is because oxygen typically has an oxidation number of -2, and hydrogen has an oxidation number of +1. In this case, there is one oxygen atom and one hydrogen atom, resulting in an overall oxidation number of -1.
In CrO3, the oxidation number of chromium (Cr) is +6 and the oxidation number of oxygen (O) is -2. This is because oxygen typically has an oxidation number of -2, and there are three oxygen atoms in CrO3 to give a total charge of -6. To balance the charge, the chromium atom must have an oxidation number of +6.
The oxidation number of the carbon atom in isopropyl alcohol (C3H8O) is -2, and for the oxygen atom, it is -2. The hydrogen atoms each have an oxidation number of +1.
The oxidation number of NO3- is -1. Each oxygen atom typically has an oxidation number of -2, totaling -6 for the three oxygen atoms. Since the overall charge of the nitrate ion is -1, the nitrogen atom must have an oxidation number of +5 to balance the charge.
