Question

if electron affinity decreases down a group why does chlorine have more electron affinity than fluorine?​

Answer 1

Answer:

the electron affinity of the fluorine is less than chlorine because the size of fluorine is too small as size decreases from left to right inside period, whereas chlorine has a larger size to accommodate electrons hence electron affinity of chlorine is more than fluorine.

hope it helps

if u are satisfied with my answer mark me as brain list

Explanation:

Answer 2

Answer:

well this is an exceptional case where chlorine has greater electron affinity value than fluorine this is because of the greater size of chlorine molecule and lesser lone pair repulsion whereas fluorine is a very small size molecule and has greater lone pair-lone pair repulsion..

hope it helps...

fluorine releases less energy on the addition of electrons means it has lesser affinity for electrons while chlorine has greater..
