Electron gain enthalpy may be ________(a) exothermic(b) endothermic(c)

1.	Electron gain enthalpy may be ________(a) exothermic(b) endothermic(c) both exothermic and endothermic(d) always zeroThis question was posed to me in an online interview.The origin of the question is Ionic or Electrovalent Bond topic in portion Chemical Bonding and Molecular Structure of Chemistry – Class 11
Answer» Correct ANSWER is (c) both exothermic and endothermic Easiest explanation: Electron GAIN enthalpy is the enthalpy change for an atom in the ground state to gain an electron. In the CASE of an exothermic REACTION, the VALUE of electron gain enthalpy is negative, which means that it is releasing energy and vice-versa when it’s positive.
