The molar enthalpy change accompanying the removal of an electron from a gas phase atom or ion in its ground state is called?
- Electron gain enthalpy
-
Ionization enthalpy
- Enthalpy change
- Enthalpic gas removal
The correct answer is: 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.
