Chemical Model Animation of O3 Losing an Oxygen Atom to a Radical

Ozone is very reactive. It easily loses the third oxygen atom in the presence of other highly reactive compounds called radicals, which contain chlorine, hydrogen, nitrogen, or bromine. Minute quantities of these radicals can cause large decreases in ozone because they are not consumed in the reaction. This is called a catalytic cycle.
