Question

Ozone is allotrope vs isotope of oxygen or compound of oxygen

Answer 1

Triatomic oxygen (ozone, O3), is a very reactive allotrope of oxygen that is destructive to materials like rubber and fabrics and is also damaging to lung tissue. ... Ozone is formed near the Earth's surface by the photochemical disintegration of nitrogen dioxide from the exhaust of automobiles.

Ozone is the much more reactiveallotrope of oxygen with the formula O3. Regular oxygen is diatomic. ... It is more reactive due to three oxygenatoms sharing the electrons which were normally shared by two oxygenatoms. Not a stable relationship.
