How are EAN rules calculated?

The total number of electrons present with the central metal atom or ion in the coordination complex plus the total number of electrons donated by the ligand is called the effective atomic number (EAN). The formula for calculating EAN is as follows.The EAN for a given complex is \[{{[Cu{{(N{{H}_{3}})}_{4}}]}^{2+}}\] as follows.
