Ozone is a form of oxygen. But unlike oxygen (O2), ozone (O3) is not a stable gas. Ozone is highly reactive and unstable
- corrosive and capable of damaging living cells. Ozone consists of three oxygen atoms. Ground-level ozone can be harmful
at high concentrations and is a regulated pollutant. NOTE: Ozone occurs naturally in the Earth’s upper atmosphere (stratosphere).
It protects life on Earth from the sun’s harmful ultraviolet (UV) rays. This is the good ozone.
