+3
The oxidation number for O in K2O is -2. Oxygen typically has an oxidation number of -2 in most compounds. Since there are two oxygen atoms in K2O, the total oxidation number contributed by the oxygen atoms is -4.
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.
The oxidation state of Na in Na2O2 is +1, as each Na atom carries a +1 charge while the O atoms carry a -1 charge. In KO2, the oxidation state of K is +1, similar to Na2O2, as each K atom carries a +1 charge while the O atoms carry a -1/2 charge.
The oxidation number for H is +1, and the oxidation number for O is -1.
In N2O5, the oxidation number of N (nitrogen) is +5 and the oxidation number of O (oxygen) is -2.
KO2 is rare and is called potassium superoxide. It consists of K+ ion and O^2- ion. In this case, the oxidation number of O would be 1-. If, however, you meant to ask about K2O (potassium oxide), then the oxidation number of O would be 2-

The central carbon atom has an oxidation number of -2 (O is -2, H is +1)
The oxidation number of oxygen (O) in most compounds, including sulfate (SO4), is typically -2. In Na2SO4, sodium (Na) has an oxidation number of +1. To calculate the oxidation number of oxygen in the compound, you would use the equation: 2(oxidation number of Na) + oxidation number of S + 4(oxidation number of O) = 0. By plugging in the known values, you can solve for the oxidation number of oxygen in Na2SO4.
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)
+1 for Na +5 for N -2 for each O
The oxidation number of Li in Li2 is +1. The oxidation number of O in Li2O is -2.
Rb has an oxidation number of +1, Cl has an oxidation number of -1, and O has an oxidation number of -2 based on common rules. Therefore, the oxidation number for RbClO would be +1 for Rb, -1 for Cl, and -2 for O.
