Answer:A
Out of the elements F, Cl, Br and I, which is the most electronegative element?
A. F B. Cl C. Br D. I
Explanation: The electronegativity decreases as we move down a group because the ability to gain electrons decreases down a group. This is because of the decrease in the effective nuclear charge experienced by the valence electrons since a new shell is added in each group.
