What are Fajans rules explain?
Fajans’ rule predicts whether a chemical bond will be covalent or ionic….Fajans’ Rule can be summarized as:
| Ionic Characteristic | Covalent Characteristic |
|---|---|
| Large Cation | Small Cation |
| Small Anion | Large Anion |
| Small-charge | Large Charge |
What is fajans rule Class 11 Ncert?
The rule says that for cations with same charge and size, the cation with electronic configuration (n−1)dnns0which is found in transition elements have greater covalent character than the cation with electronic configuration ns2np6 which is found in alkali or alkali earth metals.

What are the Fajans’rules?
He has a master’s degree in Physics and is pursuing his doctorate study. Fajans’ rules state that polarization changes ionic compounds under three specific conditions. Discover the conditions and explore Fajans’ rules for chemical bonds and polarization consequences.
What is an example of Fajans’ Law?
For example, an aluminium atom with a+3 charge has a relatively larger positive charge. Then, this positive charge exerts an attractive force on the electron cloud of the other ion which has accepted the electrons from the aluminum positive ion. Whether a chemical bond will be converted into covalent or ionic is predicted by the Fajans’ law.
What are Fajans’rules of polarization?
Fajans’ rules state that polarization changes ionic compounds under three specific conditions. Discover the conditions and explore Fajans’ rules for chemical bonds and polarization consequences. Updated: 01/05/2022 Before going into discussion of Fajans’ rules, we need to first talk a little bit about polarization and deformation of ions.
What are fajan’s rules of covalent nature?
This condition is more or less similar to the covalent bonding. Fajan’s rules were developed based on the concept: “the greater the polarization of anion, the greater is the covalent nature”. There are two factors which are crucial in deciding the extent of polarization as mentioned below.
