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
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
- 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.
