$F$

Vedclass · Answer

(A) The electron affinity generally increases across a period from left to right due to an increase in effective nuclear charge and a decrease in atomic size. Among the given elements ($C$,$N$,$O$,$F$),$F$ has the highest effective nuclear charge and the smallest atomic size. Although $Cl$ has the highest electron affinity in the entire periodic table,among the provided options,$F$ has the highest $1^{st}$ electron affinity.

List-$I$ (Element)	List-$II$ (Electron gain enthalpy in $kJ \ mol^{-1}$)
$(A)$ $F$	$(I)$ $-141$
$(B)$ $Cl$	$(II)$ $-328$
$(C)$ $O$	$(III)$ $-200$
$(D)$ $S$	$(IV)$ $-349$
