Ozone (or trioxygen) is an inorganic molecule with the chemical formula O 3. It is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope O 2, breaking down in the lower atmosphere to O 2 (dioxygen). Ozone is formed from dioxygen … See more The trivial name ozone is the most commonly used and preferred IUPAC name.
