Ozone (O3) is responsible for that strong burnt-air smell that often comes after a lightning storm.
More importantly, it forms a thin protective layer in the upper atmosphere that helps block dangerous UV (ultraviolet) rays from penetrating down to the Earth's surface, where they would lead to problems such as skin cancer.
O3 is not an element, but a molecule. It is known as ozone and is made up of three oxygen atoms.
Ozone consists of three oxygen atoms (symbol is O3).
O2 is just an oxygen molecule.
O3 is a molecule / compound, not element
O2 represents a molecule of oxygen gas, consisting of two oxygen atoms bonded together. O and H2 represent single atoms of oxygen and hydrogen, respectively. O3 represents a molecule of ozone, consisting of three oxygen atoms bonded together.
Ozone is a molecule. Its formula is O3.

O3 or Ozone
Ozone consists of three oxygen atoms (symbol is O3).
The molecular formula of ozone is O3 because an ozone molecule consists of three oxygen atoms bonded together. The presence of three oxygen atoms in each molecule gives rise to the chemical formula O3.
O2 is just an oxygen molecule.
