Question

What is Fajans Rule?
Give statement

Answer 1

Answer:

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

The Fajan's rule is used to predict whether a chemical bond will be covalent or ionic, and depend on the charge on the cation and the relative sizes of the cation and anion.

Explanation:

Here is an example,

NaCl is correctly predicted to be ionic since Na+ is a larger ion with a low charge and Cl− is a smaller anion.

Answer 2

Answer:

By Fajans' 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.
