Question

Electron affinity of $Cl$ is greater than that of $F.$

• A. True
• B. False

Answer 1

The correct option is A True

$Cl$ has higher electron affinity than $F.$ On comparing chloride ion with fluoride ion we find that electron density per unit volume in fluoride ion $\left(F^{-}\right)$ is more than in chloride $\left(C{l}^{-}\right)$ "ion. This means that coming electron in fluorine atom finds less attraction than in chlorine atom. Consequently, electron affinity of chlorine is higher than that of fluorine.
