What is the EAN rule in chemistry?
What does EAN stand for?
- Effective atomic number. Written By: Effective atomic number (EAN), number that represents the total number of electrons surrounding the nucleus of a metal atom in a metal complex.
What is effective atomic number (EAN)?
- The sum of the electrons on the metal plus the electrons donated from the ligands was called the effective atomic number (EAN), and when it was equal to 36 (Kr), 54 (Xe) and 86 (Rn), the EAN rule is said to be obeyed.
How do you calculate the eneean rule?
- EAN rule is often referred to as the “18-electron rule”. It can be calculated using the formula as the sum of electrons on the metal ion and the number of electrons denoted by ligands. Was this answer helpful?
