What is the correct chemical form of atmospheric oxygen?
Answer and explanation
Correct answer: O₂
The oxygen gas normally present in air is a diatomic molecule, meaning that two oxygen atoms are bonded together; its formula is O₂. Thus, option C is correct. O₃ is ozone, a triatomic form that occurs in much smaller quantities and is concentrated in the ozone layer. CO₂ is carbon dioxide, and N₂ is nitrogen, so neither represents atmospheric oxygen.
