Question

Which pair of element has maximum electronegativity difference? * (a) Li and F (b) Na and F (c) Na and Br (d) Na and Cl

Answer 1

Answer:

Na and F

Explanation:

The general peroidic table electronegativity trend says that moving down the group electronegativity of element decreases.

So in the atoms Li , F , Na , Cl , Br the most electronegative is F and the least electronegative or most electropositive is Na .

Which implies out of all the combinations Na and F have most electronegativity difference between them.
