उत्तर
ozone and oxygen
Explanation:
Oxygen is found in the atmosphere in two forms, as diatomic molecule (O2) and as triatomic ozone (O3). Normally elemental oxygen is found in the form of a diatomic molecule in the atmosphere. Ozone is not stable near the earth’s surface and is present 18¬50 km above in the atmosphere (stratosphere) as a thick blanket called ozonosphere or ozone shield.
