Webhydroxyl radical. These include the chlorofluorocarbons (CFC's), nitrous oxide (N 2O) and carbon dioxide (CO 2). The rate of methane (CH 4) oxidation by OH is also very slow, between 100 and 1000 times slower than other organic compounds. This is why methane concentrations in the atmosphere can reach around 1.7 ppm (1.7 µmol mol-1), a value WebA radical is a molecule or atom that has at least one unpaired electron (one electron is in an orbit by itself), but this moelcule or atom does not carry a charge like an ion because the number of orbiting electrons still matches the number of protons in the nucleus.; however …
