  • Scope was later broadened to include hydrogen transfer
2

Electron Transfer Theory

  • Modern definition based on electron transfer
  • Oxidation: Loss of electrons by any species
  • Reduction: Gain of electrons by any species
3

Oxidation Numbers

  • Oxidation number is the apparent charge on an atom in a compound
  • Based on assumption of complete electron transfer to more electronegative atom
  • Used for book-keeping electrons in covalent compounds
4

Rules for Assigning Oxidation Numbers

  • Free elements have oxidation number = 0
  • Monatomic ions: oxidation number = charge on ion
  • Alkali metals = +1, Alkaline earth metals = +2 in compounds
