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.

$A. S \rightarrow S^{-}$	$P. \text{Endothermic process}$
$B. N^{-} \rightarrow N$	$Q. \text{Exothermic process}$
$C. O^{-} \rightarrow O^{2-}$	$R. \text{Inert gas configuration in product}$
$D. P \rightarrow P^{-}$	$S. \text{Half filled configuration in product}$

List-$I$	List-$II$
$(1)$ Active non-metal with high electron gain enthalpy.	$(A)$ $Na$
$(2)$ Soft metal with low ionization enthalpy.	$(B)$ $Sb$
$(3)$ Metalloid that forms ${M_2}{O_3}$ type oxide.	$(C)$ $He$
$(4)$ Chemically inert gas.	$(D)$ $Cl$
