For the electron affinity of halogens (with `-ve` sign), which of the following is correct?

A

Br gt F

B

F gt Cl

C

Br gt Cl

D

F gt I

Text Solution

Verified by Experts

The correct Answer is:
D
`{:("Halogen",F,Cl,Br,I),("Electron affinity (eV)",-3.6,-3.8,-3.5,-3.2):}`
The low value of electron affinity of fluorine is probably due to small size of fluorine atom i.e., electron density is high which hinders the addition of an extra electron.
