The normal formula for oxygen is O2.
Oxygen typically exists as a diatomic molecule, meaning it consists of two oxygen atoms bonded together. This form, also known as dioxygen, is the most common and stable form of oxygen at standard temperature and pressure (STP). Dioxygen is a colorless, odorless, and tasteless gas.
While oxygen primarily exists as O2, other forms exist, though less commonly:
- Ozone (O3): This is another allotrope of oxygen. It's significantly less stable than O2 and is known for its role in absorbing ultraviolet (UV) radiation in the Earth's atmosphere.
Therefore, although ozone (O3) is a form of oxygen, the most accurate and "normal" formula for oxygen is O2.
