Hi,

Ozone is a molecule formed from three atoms of oxygen.
It is a product of ultraviolet radiations acting on the oxygen molecule and splitting it into free oxygen atoms. These atoms combine with molecular oxygen to form ozone.
Ozone is a gas like oxygen. However, oxygen is necessary for respiration, while ozone is poisonous when inhaled.
