Which statement is correct regarding the chemical identity of ozone in the atmosphere?
Answer and explanation
Correct answer: It is a triatomic form of oxygen
Ozone has the molecular formula O₃, so each molecule contains three oxygen atoms and it is called a triatomic allotrope of oxygen. Option A is therefore chemically correct. Nitrogen is N₂ in its usual atmospheric form, dust is a collection of solid particles rather than a chemical compound, and argon is a separate inert element. Ozone also absorbs much ultraviolet radiation, but that role does not change its identity.
