Metals:
* Oxides: Oxygen bonds with most metals to form oxides, which are ionic compounds. Examples include iron oxide (rust), aluminum oxide (found in bauxite ore), and sodium oxide (used in glassmaking).
* Hydroxides: Oxygen can also combine with hydrogen and metals to form hydroxides, which are also ionic compounds. Examples include sodium hydroxide (lye), potassium hydroxide, and calcium hydroxide (found in cement).
Nonmetals:
* Water (H₂O): Oxygen bonds with hydrogen to form water, a vital compound for life.
* Carbon dioxide (CO₂): Oxygen bonds with carbon to form carbon dioxide, a greenhouse gas released during respiration and combustion.
* Sulfur dioxide (SO₂): Oxygen bonds with sulfur to form sulfur dioxide, a major air pollutant.
* Nitrogen oxides (NOₓ): Oxygen bonds with nitrogen to form nitrogen oxides, which contribute to smog and acid rain.
Other:
* Ozone (O₃): Oxygen can bond with itself to form ozone, a molecule that absorbs harmful ultraviolet radiation from the sun.
* Peroxides: Oxygen can form compounds with other elements called peroxides, which contain the peroxide ion (O₂²⁻). Examples include hydrogen peroxide (H₂O₂), a common disinfectant.
Note: This is not an exhaustive list, as oxygen can bond with a wide variety of elements and form numerous compounds.
