What is the value of electron gain enthalpy of $Na^{+}$ if $IE_{1}$ of $Na$ is $5.1 \ eV$? .......... $eV$

Which of the following represents the correct order of increasing electron gain enthalpy (with negative sign) for the elements?
$a.$ Nitrogen
$b.$ Phosphorus
$c.$ Chlorine
$d.$ Fluorine

The increasing order of electron affinity for the given electronic configurations of elements is:
$I. 1s^2 2s^2 2p^6 3s^2 3p^5$
$II. 1s^2 2s^2 2p^3$
$III. 1s^2 2s^2 2p^5$
$IV. 1s^2 2s^2 2p^6 3s^1$

The electron affinity values of elements $A, B, C$ and $D$ are respectively $-135, -60, -200$ and $-348 \ kJ \ mol^{-1}$. The outer electronic configuration of element $B$ is

Which of the following represents the correct order of electron affinity?

Match the following:

List-$I$ (Element)	List-$II$ ($\Delta_{eg}H$ in $kJ \ mol^{-1}$)
$A$. $O$	$I$. $-200$
$B$. $F$	$II$. $-349$
$C$. $Cl$	$III$. $-141$
$D$. $S$	$IV$. $-328$
	$V$. $+48$

The correct answer is:
