What is ozone? Ozone, or O3, is a gas containing three oxygen atoms. Ozone is an unstable chemical that is highly reactive with other gases in the air. Ozone at ground level is unhealthy and is a component of smog. Ozone found high up in the atmosphere, called stratospheric ozone, protects us by shielding us from harmful ultraviolet (UV) light.
Ozone is formed naturally in Earth's upper atmosphere. When the oxygen gas (O2) in the atmosphere is exposed to ultraviolet light, the chemical bond between the two oxygen atoms is broken. The extra oxygen atom bonds with an existing O2 molecule in the atmosphere, forming ozone (O3). Ozone is also formed from car exhaust, which contains nitric oxide (2NO), an unstable nitrogen and oxygen molecule.
