WebEffective atomic number is defined as the total number of electrons around the metal (its own electrons + the electrons donated by the ligands). It is abbreviated as EAN or Zeff, and effective atomic number rule importance in coordination chemistry is unparalleled. It is also referred to as the Sidgwick rule as Nevil V. Sidgwick coined it. Web'Effective atomic number' (EAN): It is the total number of electrons around the central metal ion present in a complex and calculated as the sum of the electrons on the metal ion and the number of electrons donated by the ligands. It can be calculated using the formula E A N = Z − X + Y Z = atomic number of the metal
