Type: MCQ-conceptual-Hard-Class 11

Which of the following statements regarding electron gain enthalpy and the periodic properties of elements is correct?

A

Electron gain enthalpy is always exothermic for all elements.

B

Electron gain enthalpy can be either endothermic or exothermic depending on the element.

C

Elements in Group 16 have a higher electron gain enthalpy than those in Group 17.

D

Electron gain enthalpy values are consistent across all periods of the periodic table.

Correct Answer

Option B

Detailed Explanation
