Free radicals react with molecules, atoms,
other radicals in long series of chain reactions. A radical is formed in
the atmosphere through photolysis or chemical reaction. Radicals are very
reactive and will pull atoms or electrons from other molecules to fill
their outer valance shell. New radicals may formed from the original
molecule which then react with another molecule, etc. This reaction
propagates from one species to another until a termination reaction
occurs. The termination reaction usually involves the reaction of two free
radicals to form a stable product.
