- UV radiation breaks off a chlorine atom from a CFC molecule.
- The chlorine atom attacks an ozone molecule (), breaking it apart and destroying the ozone.
- The result is an ordinary oxygen molecule () and a chlorine monoxide molecule (ClO).
- The chlorine monoxide molecule (ClO) is attacked by a free oxygen atom releasing the chlorine atom and forming an ordinary oxygen molecule ().
- The chlorine atom is now free to attack and destroy another ozone molecule (). One chlorine atom can repeat this destructive cycle thousands of times.
