Oxidation state of K in KO2 is - 0.5 because its structure is K-O=O .
+1. the compound in question could be K2O or possibly K2O2 in both K is +1
- 1/2 as KO2 is a superoxide
0 and 1 oxidation states
-2 oxidation state
-2
Ru has oxidation number +8, O has oxidation number of -2
The overall oxidation number is -2 so the average oxidation number of O is -1.
Oxidation number of chlorine is +7. oxidation number of O is -2.
The oxidation number for H is +1, and the oxidation number for O is -1.
Oxidation number of Si is +4.Oxidation number of O 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-
