Compare the properties of the gaseous forms of oxygen and the oxygen free radical

  • Free radical: A species containing at least one unpaired electron.
  • An oxygen free radical has six electrons in its outer shell, with two of these being unpaired:
  • The unpaired electrons make radicals very reactive.
  • When ultraviolet radiation splits an oxygen molecule, two oxygen free radicals are formed.
  • Oxygen free radicals are more reactive than ozone molecules, which are more reactive than oxygen molecules.
