Question

Among ionization enthalpy electron gain enthalpy and electronegativity which is not a measurable quantity

Answer 1

Answer: Electron gain enthalpy of an atom cannot be measured.

Explanation:

It is not a measurable quantity. It is only a relative number. On the other hand, electron gain enthalpy is hte enthalpy change that takes place when an electron is added to a neutral gaseous atom to form an anion. And hence it cannot be measured.

Answer 2
