Question

which element has the highest electronegativity? fluorine (f) iodine (i) chlorine (cl) bromine (br)

Explanation:

Electronegativity generally increases across a period and decreases down a group in the periodic table. Fluorine (F), Iodine (I), Chlorine (Cl), and Bromine (Br) are all halogens (Group 17). As we move up the group (from I, Br, Cl to F), electronegativity increases because the atomic radius decreases, so the nucleus can attract electrons more strongly. Among these, Fluorine is at the top of Group 17, so it has the highest electronegativity.

Answer:

A. Fluorine (F)
