Oxides:
* Metal oxides: These are formed when metals react with oxygen. Examples include iron oxide (rust), aluminum oxide, and calcium oxide.
* Non-metal oxides: These are formed when non-metals react with oxygen. Examples include carbon dioxide, sulfur dioxide, and nitrogen dioxide.
Other compounds:
* Water (H₂O): One of the most important compounds on Earth.
* Organic compounds: Oxygen is a key component of many organic compounds, including carbohydrates, lipids, proteins, and nucleic acids.
* Peroxides: These contain the peroxide anion (O₂²⁻), such as hydrogen peroxide (H₂O₂).
* Superoxides: These contain the superoxide anion (O₂⁻), such as potassium superoxide (KO₂).
* Ozone (O₃): A triatomic molecule that is a powerful oxidant found in the Earth's atmosphere.
Important Note: Oxygen can form compounds with nearly every element except for some noble gases like helium and neon.
Examples of specific compounds:
* Carbon monoxide (CO): A poisonous gas.
* Carbon dioxide (CO₂): A greenhouse gas essential for plant photosynthesis.
* Sodium chloride (NaCl): Table salt, formed by the reaction of sodium with chlorine.
* Sulfuric acid (H₂SO₄): A strong acid used in many industrial processes.
* Nitric acid (HNO₃): A strong acid used in the production of fertilizers and explosives.
This is just a small sampling of the many compounds oxygen can form. The diversity and importance of these compounds highlight the essential role of oxygen in chemistry and biology.
