Which one of the following has the highest ionic character?
Correct answer: D. CsF
- A. HF
- B. NaCl
- C. HCl
- D. CsF
Explanation
CsF has the highest ionic character because Cs is the most electropositive element and Fluorine is the most electronegative element. Hence the bond that would be formed between the most electropositive and the most electronegative elements would be very strong and will have the highest ionic character.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
