"WebbAns: The energy released by an atom when it gains an electron from outside an atom or ion to form a negative ion (or anion) is called electron gain enthalpy (? eg H). Unit of electron gain enthalpy is kJ/ mol. In some cases, like in noble gas, atoms do not have any attraction to gain an electron. In that case energy has to be supplied. For example, " - The push of gas atoms is called
