Question

HEY FRND !! NEED UR HELP !!

EXPLAIN FAJAN'S RULE ??? IN EASY WAY .........

THANKYOU☺☺☺

Answer 1

To use Fajans' Rules, assume your binary compound is ionic and identify the potential cation and anion. ByFajans' Rules, compounds are more likely to be ionic if: there is a small positive charge on the cation, the cation is large, and the anion is small.

Answer 2

FAJAN'S Rule :

It is nothing it just Tells that Any Compound Whether it is Ionic, Metallic or any compound they Try To BECOME COVALENT BOND...

Ex. ZnCl2, NaCl all these compound shows Covalent Character sometime

So Fazan Rule States four thing :

1) Compound should have small Cation.. Like Na, Mg, Ca, K etc. etc.

2) Compound should have large Anion.. like F, Cl, I etc etc..

3) Max Charge Density.. : Charge Density is Calculated by q1*q2 and here q is charge on both the Atoms..

Like : MgCl2 --> Mg+2 + 2Cl-

q1 - 2

q2= 2

q1*q2 = 4

4) Psudo nobel Configuration : When element have more or less than 10 electron in d orbital and 14 electron in f orbital then it is said to be Psuod Nobel Configuration

So Here FAJAN'S RULE.. ENDS

Thank You
