The number of replaceable electrons in an atom is called its valency.

Examples

  • Monovalent - Hydrogen
  • Divalent - Oxygen

  • Valency = 8 - Number of electron in last shell [When number of electrons in last shell > 4]

  • Valency = Number of electron in last shell [When number of electrons in last shell < 4]

Thanks !
