The correct order of electron gain enthalpy is

Which of the following atoms should have the highest $1^{st}$ electron affinity?

Which of the following is correct for the electron affinity of halogens?

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 electron affinities of halogens are $F = 322, Cl = 349, Br = 324, I = 295 \ kJ \ mol^{-1}$. The higher value for $Cl$ as compared to that of $F$ is due to :-

Which of the following has the highest electron affinity $(EA)$?
