Element having maximum electron affinity is
Options
(a) F₂
(b) Cl₂
(c) Br₂
(d) I₂
Correct Answer:
Cl₂
Explanation:
Electron affinity generally decreases down the group due to decrease in the value of electronegativity down the group. But Cl has more electron affinity than F atom, this is due to the interelectronic repulsion in the small sized fluorine . So the correct order is : Cl > F > Br > I.
