Carbon dioxide and water (H2O)
the most common oxidation number for oxygen is -2.
It is a gas. Generally it shows -2 oxidation number.
Examples of compounds include sulfate (SO4^2-), nitrate (NO3^-), phosphate (PO4^3-), carbonate (CO3^2-), and chromate (CrO4^2-), which all contain oxygen in their polyatomic ions.
Typically in compounds it is -2 (oxide ion) - other values include zero (in O2 and O3)
All compounds that end in carbonate contain the CO3^2- polyatomic ion. This ion consists of one carbon atom bonded to three oxygen atoms, carrying a charge of -2. Examples of carbonate compounds include sodium carbonate (Na2CO3) and calcium carbonate (CaCO3).

The oxidation number for oxygen in most compounds is -2.
The two most common compounds in the Earth's atmosphere are nitrogen gas (N2) and oxygen gas (O2), which together make up about 99% of the total volume of gases.
Oxygen can have oxidation states of -2, -1, 0, 1, 2 in chemical compounds.
Gold forms compounds with elements such as oxygen, sulfur, and chlorine. Common compounds include gold oxide (Au2O3), gold sulfide (Au2S), and gold chloride (AuCl3). These compounds are often used in various industrial applications.
The oxidation number of oxygen is -2 in most of its compounds
In most compounds oxygen will have an oxidation state of -2. The only exceptions are peroxides (-1), superoxides (-1/2), and compounds in which oxygen bonds with fluorine (+1 or +2).
Oxygen has the valency of 2 in most of the compounds.
