1.	What is EAN rule ?
Answer» Solution :‘Every central metal atom or ion in a complex has a tendency to acquire effective atomic NUMBER (EAN) of next inert gas.’EAN of metal in- a complex = At. No. - Oxidation state `+2x X` COORDINATION number. Ex.: EAN of Fe in `K_4 \|Fe (CN)_6]` =(26 - 2) + 2 x 6 = 36 (At. No. of Krypton)
