$Cl > S > Li > Na$

Vedclass · Answer

(B) The electron gain enthalpy becomes more negative as we move from left to right across a period and becomes less negative as we move down a group. For the given elements: $Cl$ (Group $17$,Period $3$) has the highest negative electron gain enthalpy. $S$ (Group $16$,Period $3$) follows $Cl$. $Li$ (Group $1$,Period $2$) and $Na$ (Group $1$,Period $3$) have low negative values,with $Li$ being more negative than $Na$ due to its smaller size. Thus,the correct order of negative electron gain enthalpy is $Cl > S > Li > Na$.

The order of negative electron gain enthalpy of $Li$,$Na$,$S$,$Cl$ is
