The oxygen in the air forms ozone in presence of UV rays is an example of a chemical change.
What is a chemical change?
A typically irreversible chemical reaction that results in the production of at least one new substance via rearranging of the atoms of one or more substances and a change in their chemical characteristics or composition.
Chemical reaction showing the formation of ozone from oxygen in the atmosphere:
By using higher frequency UV light, one oxygen molecule is divided (photolyzed) into two oxygen atoms:
O₂ + ℎν → 2O
(<242 nm)
The resulting ozone molecule is formed when each oxygen atom swiftly joins with an oxygen molecule:
O + O₂ → O₃
