  • Oxidation Numbers
    • An element has been oxidised when its oxidation number increases
      • Further more, if its oxidation number has decreased, then it has been reduced
        • Oxidation is lose. Reduction is gain.
    • The oxidation number indicates a formal change of a chemically combined particle in a compound
      • Oxidation is lose. Reduction is gain.
    • When metals react, they are normally oxidised.
      • When non metals react, they are normally reduced
    • The oxidation number for metals is their group number or valency
      • The oxidation number for Non metals is generally 8 - their group number
