what is difference between valency and oxidation state with egs and detail.

Asked by Nidar Zaman Kha...(student) , on 9/10/12


  • Valency is the maximum number of electrons which an atom can lose or gainwhile oxidation state is the actual number of electrons which the element lose or gain to form a molecule.
  • Valency is the property of an isolated atom while oxidation state is calculated for an atom present in a molecule i.e. in bonded state.
  • Oxidation state may or may not be equal to the valency.
  • Valency of an element always remains the same, while its oxidation state may be different in different molecules.
