The chemical formula of ozone is O3, indicating that it is composed of three oxygen atoms. Ozone is a triatomic molecule composed of three oxygen atoms. Each oxygen atom in ozone is bound to the other two oxygen atoms by double bonds, resulting in a bent molecular geometry.
Formation of Ozone:
Oxygen molecule (O2)+Ultraviolet radiation (UV)→Ozone (O3)
Decomposition of Ozone:
Ozone (O3)→Oxygen molecule (O2)+Oxygen atom (O)
These reactions occur largely in the stratosphere and play an important role in the creation and maintenance of the ozone layer.
