    No. Ozone is an element (oxygen), and an aerosol is a mixture of compounds.

    Thank you! One more question, can a compound exist as a mixture? If so, what are the examples?

    No. The elements must react together to form a compound. If they have not reacted together (perhaps because conditions are not favourable, say too cold) it is a mixture. An example of that would be a gaseous mixture of oxygen and hydrogen in the absence of ignition. After the reaction they form the compound known as water.
