Explain Fajan's Rule.

Fajans' Rules are used to predict whether a chemical bond will be covalent or ionic. This depends on: - the charge on the cation - the size of the cation - the size of the anion

Fajan's rules, proposed by Kazimierz Fajans in 1923, describe how ion size, charge, and electron distribution affect the ionic and covalent character of chemical bonds. They indicate why compounds often display covalent characteristics despite theoretically being ionic. Factors such as ion size, charge, and polarizability play crucial roles. ;

Fajan's Rule is used to predict whether a bond will be ionic or covalent based on the charge and size of the cation and the size of the anion. Higher charge and smaller size of the cation tend to increase covalent character, while larger anions can lead to similar results. This helps in understanding the nature of chemical bonding in compounds more accurately.
