Solution
Ozone is an allotrope of oxygen.
Explanation:
Ozone is a special form of oxygen in which three oxygen atoms are bonded together to form a molecule with the formula O3. It is not a compound or isotope but an allotrope because it is a different structural form of the same element, oxygen. Ozone is found in the upper atmosphere and protects us from harmful ultraviolet rays by absorbing them. It is formed naturally by the action of ultraviolet rays on oxygen gas.
