Oxidation:

  • Oxidation is a process which involves the addition of oxygen or any electronegative element or the removal of hydrogen or any electropositive element.  
  • In terms of electrons, oxidation is defined as the process in which an atom or ion loses one or more electrons.
  • Oxidation occurs when the oxidation state of a molecule, atom or ion is increased. The opposite process is called reduction, which occurs when there is a gain of electrons or the oxidation state of an atom, molecule, or ion decreases.
