what is the EAN of Ni in the complex ion [ Ni(NH3)6 ]^2+ ?


Expert Answer

Step 1

Effective atomic number (EAN):

Ligands are attached to the central metal ion through donar atoms. each donar atom donates one electron pair to the central metal ion. According to sidgwick theory EAN defined as the resultant number of electrons with the metal atom or ion after gaining electrons from the donar atoms of the ligands.

Effective atomic number generally coincides with the atomic number of the inert gases. Therefore, the complex is stabel.
