Which is a correct statement according to Fajan's rule
Every bond is purely ionic.
Every covalent bond has some amount of ionic bond character
Every ionic bond has some amount of covalent character.
None of these.
The Fajans’ rule predicts whether a chemical bond will be covalent or ionic. A few ionic bonds have partial covalent characteristics, which were first discussed by Kazimierz
Fajans in 1923. He was able to predict ionic or covalent bonding with attributes like ionic and atomic radius with the help of X-ray crystallography. So option 3 is correct.
