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. WebThe EAN rule or effective atomic number rule can be calculated from the following equation: {\rm {EAN}} = {\rm {Z}}-- {\rm {x}} + {\rm {2nL}} EAN = Z −−x+2nL. Where, Z is the atomic number of the metal in the complex. x is the oxidation state of the metal in the complex. n is the number of the ligands. L is the number of co-ordinate bonds ...
WebThe EAN rule is also known as the "18-electron rule." It is computed as the sum of electrons on the metal ion and the number of electrons designated by ligands using the formula: EAN = ( metal ' s atomic number) + ( number of ligands × electrons provided by each ligand) – ( metal ' s positive oxidation state) Or we can also say that: EAN ...
