-1 oxidation state. This ion should be called Kallide
The oxidation state of K in K2O2 is +1. In this compound, each K atom has a +1 oxidation state and each O atom has a -1 oxidation state.
The oxidation state of chloride (Cl) is -1. As a halogen, chloride is usually found with an oxidation state of -1 in most compounds.
In KCIO2, the overall charge of the compound is zero because potassium (K) has a +1 charge, oxygen (O) has a -2 charge, and the sum of the oxidation states must equal zero. Therefore, the oxidation state of chlorine (Cl) in KCIO2 is +5.
oxidation state
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.
In KNO3, the nitrogen atom has an oxidation state of +5. This is because potassium (K) is in Group 1 and has an oxidation state of +1, and oxygen (O) is in Group 6 and has an oxidation state of -2. To balance the charges, nitrogen must have an oxidation state of +5.
When the metal can exist in more than one oxidation state
The oxidation number for K in KCl is +1, as alkali metals (Group 1 elements) typically have a +1 oxidation state. For Cl in KCl, the oxidation number is -1, as halogens (Group 17 elements) typically have a -1 oxidation state when they form ionic compounds.
The oxidation number of KF is +1 for potassium (K) and -1 for fluorine (F). This is because alkali metals like potassium typically have an oxidation state of +1, while halogens like fluorine have an oxidation state of -1 in ionic compounds.

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 CuCl2, the oxidation state of copper (Cu) is +2, and the oxidation state of chlorine (Cl) is -1. This is because the overall charge of the compound is 0, and there are two chloride ions each with an oxidation state of -1 to balance the +2 charge of copper.
