The $EA$ of $'F'$ atom is more than $'Cl'$ atom

Vedclass · Answer

(B) . Ionic mobility depends on the size of the hydrated ion. $Na^{+}$ has a smaller charge than $Mg^{2+}$,so it is less hydrated and has higher mobility. This statement is correct.$B$. The electron affinity $(EA)$ of $Cl$ is higher than $F$ due to the small size and high inter-electronic repulsion in the $2p$ subshell of $F$. Thus,the statement that $EA$ of $F$ is more than $Cl$ is incorrect.$C$. The electronic configuration of $B^{+}$ is $1s^2 2s^2$ and $C^{+}$ is $1s^2 2s^2 2p^1$. Removing an electron from the stable $2s^2$ orbital of $B^{+}$ requires more energy than from the $2p^1$ orbital of $C^{+}$. This statement is correct.$D$. $IE$ of $O^{-}$ is less than $O$ because removing an electron from a negatively charged ion is easier than from a neutral atom due to electron-electron repulsion. This statement is correct.
