NEET Chemistry Periodic Table MCQ Question
Consider the elements of Group 16 in the periodic table. If the electron gain enthalpy of oxygen is -141 kJ/mol, what would be the expected electron gain enthalpy value for sulfur, given the trend in electron gain enthalpy down the group?
-200 kJ/mol
-120 kJ/mol
-141 kJ/mol
-100 kJ/mol
Correct Answer
Detailed Explanation
In a group, electron gain enthalpy generally becomes less negative as you move down from oxygen to sulfur, due to increased atomic size and electron shielding effects.
