Question

write down the fazan rules with increase covalent character of an ionic bond ?​

Answer 1

Explanation:

When the size of a cation is smaller than a cation with the same charge, then the smaller sized cation causes a greater extent of polarization on the anion than the larger sized cation.

The polarizing capacity of a cation is related to its ionic potential (which is Z+/r) which is inversely related to the ionic radius.

Answer 2

$\large\fbox\red{Answer}$

The rule can be stated on the basis of 3 factors, which are :

Size of the ion: Smaller the size of cation, the larger the size of the anion, greater is the covalent character of the ionic bond.

The charge of Cation: Greater the charge of cation, greater is the covalent character of the ionic bond.
