Vedclass · Answer

(A) On moving down the group,the electron gain enthalpy generally decreases. Oxygen,due to its small size,experiences significant electron-electron repulsions in its relatively small $2p$-subshell. Consequently,an incoming electron is not accepted as easily as in the case of other elements in the same group,which is why oxygen has a lower electron gain enthalpy than sulfur. Therefore,the correct order of electron gain enthalpy for the group $16$ elements is $S > Se > Te > O$.

In which of the following is the electron gain enthalpy of elements correctly arranged?
