Question

WHY chlorine is the most electro affinity than flourin

Answer 1

___________________________

$\huge\sf\implies$ Yes , it is true that electron affinity of fluorine is less than chlorine .This is because the size of fluorine atom is very small as compared to that of chlorine atom and due to its small size there are strong repulsions among valence electrons and so the outer electron does not feel attraction from the nucleus.

Answer 2

Answer:

Electron affinity of fluorine is less than that of chlorine. This is due to the reason explained below:

Electron affinity of fluorine is less than that of chlorine. This is due to the reason explained below:Fluorine has seven electrons in 2p-subshell whereas chlorine has seven electrons in its 3p-subshell. 3p-subshell is relatively larger than 2p-subshell. Therefore, repulsion among the electrons will be more in the 2p-shell of fluorine than 3p-subshell in chlorine.

This is due to the reason explained below:Fluorine has seven electrons in 2p-subshell whereas chlorine has seven electrons in its 3p-subshell. 3p-subshell is relatively larger than 2p-subshell. Therefore, repulsion among the electrons will be more in the 2p-shell of fluorine than 3p-subshell in chlorine.Due to the smaller size and thus, the greater electron-electron repulsions, fluorine will not accept an incoming electron with the same as chlorine. As a result, a lesser amount of energy released is when one electron is added into the 2p-subshell of F (g) to form
