Question

The enthalpy change that occurs when an atom in the ground state gains an electron, is electron gain enthalpy.

(a) True

(b) False

I had been asked this question in semester exam.

I'm obligated to ask this question of Ionic or Electrovalent Bond topic in division Chemical Bonding and Molecular Structure of Chemistry – Class 11

Answer 1

Correct choice is (a) True

Explanation: Yes. electron gain enthalpy is the enthalpy change for an atom in the ground state to gain an electron. An atom gains an electron, thus forming negatively charged ion also known as a cation. Symbolic representation is as follows: A(g) + e^– → A(g)^–.
