Question

26 multiple choice 1 point select the most reactive element. f cl br i

Explanation:

Fluorine (F) is the most electronegative element and has a strong tendency to gain an electron. Among halogens (F, Cl, Br, I), reactivity decreases down the group. Fluorine has the smallest atomic radius and highest electronegativity in this group, making it the most reactive.

Answer:

F
