Highest electron affinity is possessed by chlorine not fluorine ????

Answer 1

Thanks and same to you.




Chlorine and Electron Affinity. As Fluorine sits atop chlorine in the periodic table, most people expect it to have the highest electron affinity, but this is not the case. Fluorine is a small atom with a small amount of space available in its 2p orbital.
Hope it's help you

Answer 2

This is because the size of fluorine is very small as compared to chlorine atom and due to its small size there are strong inner repulsion among valance electrons and so the outer electron does not feel the attraction from the nucleus .So affinity of fluorine is less than chlorine
