Question

A single atom of chlorine can destroy about = __________

Answer 1

• Ozone molecules are destroyed when chlorine and bromine atoms come into touch with them in the stratosphere.
• Before being evacuated from the stratosphere, a single chlorine atom can damage over 100,000 ozone molecules.
• Ozone can be depleted faster than it can be generated naturally.

Hence, a single atom of chlorine can destroy about 100,000 ozone molecules.
