The molar enthalpy change accompanying the removal of an electron from a gas phase atom or ion in its ground state is called?
A. Electron gain enthalpy B. Ionization enthalpy C. Enthalpy change D. Enthalpic gas removal
Correct Answer: B
Explanation
- The enthalpy change associated with the removal of the first electron from an isolated gaseous atom.
- Ionization enthalpy is the minimum amount of energy required to detach from an isolated gaseous atom the most loosely bound electron and turn it into a gaseous cation.
