Fajans' rules. From Wikipedia, the free encyclopedia. Jump to: navigation, search. In inorganic chemistry, Fajans' rules, formulated by Kazimierz Fajans in 1923, are 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

Answer 2

Hey brainly user

Here is your answer

» For a given cation, covalent character Increases with increase in size of the anion

» For a given anion, covalent character increases with a decrease in the size of the cation

» Covalent character Increseas with increasing charge either on cation or an anion

» Covalent character is higher for compounds with cations with pseudo noble gas electronic configuration
