When copper combines with oxygen to form copper oxide, the copper ion has a +2 charge. This is because copper typically forms a 2+ oxidation state when it combines with oxygen in this compound.
In terms of ionic compounds an oxide contain the oxide ion (O2-) Which is a single oxygen atom with a 2- charge. A peroxide contains the peroxide ion (O22-) which is a particle of two oxygen atoms bonded together and has a 2- charge. Unlike most normal oxides, peroxides tend to be oxidizers or at the very least, unstable. A superoxide contains the superoxide ion (O2-) which consists of two oxygen atoms bonded together and has a 1- charge. This ion is even more strongly oxidizing than the peroxide ion. In covalent compounds oxides are substances that contain oxygen in the 2- oxidation state and not bonded ot other oxygen atoms. Peroxide contain a peroxide group (O2) in which each oxygen atom is bonded to the other oxygen an to another atom, typically carbon or hydrogen. IN this case oxygen is in the 1- oxidation state.
The oxidation state for the phosphate ion (PO4) is -3. This is because oxygen typically has an oxidation state of -2 and there are four oxygen atoms in the phosphate ion. The oxidation state of phosphorus in the phosphate ion is therefore calculated as +3 to balance out the -8 charge from the four oxygen atoms.
The sulfate ion is SO42 -. The oxidation state of the sulfur is +6 (work it out!); therefore, the ion is more properly named the sulfate(VI) ion. The sulfite ion is SO32-. The oxidation state of the sulfur is +4.
The oxidation number for hydronium, H3O+, is +1 for each hydrogen atom and -1 for the oxygen atom, resulting in a total oxidation number of +1 for the ion.
An oxide ion can be oxidized to an oxygen atom by an oxidizing agent that accepts electrons from the ion, causing it to lose electrons. This process results in the formation of an oxygen atom with a positive oxidation state.

FeO is iron(II) oxide, also known as ferrous oxide, where iron has a +2 oxidation state. Fe2O3 is iron(III) oxide, also known as ferric oxide, where iron has a +3 oxidation state. This means FeO has one iron atom for each oxygen atom, while Fe2O3 has two iron atoms for every three oxygen atoms.
O2- is the formula for oxide ion. The negative symbol indicates the presence of anions and 2 represents the oxidation state.
The oxidation state of Cl in ClO is +1, because oxygen usually has an oxidation state of -2 in compounds, so Cl must have an oxidation state of +1 to balance the charge of the ion.
The sulfate ion is SO42 -. The oxidation state of the sulfur is +6 (work it out!); therefore, the ion is more properly named the sulfate(VI) ion. The sulfite ion is SO32-. The oxidation state of the sulfur is +4.
In this ion the oxidation state of sulfur is 6+ and the oxidation state of each oxygen is 2-

The oxidation number for Ti in TiO2 is +4. This is because oxygen usually has an oxidation state of -2 and there are 2 oxygen atoms in TiO2, making the combined oxidation state from the oxygen atoms -4. Therefore, the titanium atom must have an oxidation state of +4 to balance the overall charge of the compound.
