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

QUICK ANSWER…

B

DETAILS…

The molar enthalpy change accompanying the removal of an electron from a gas phase atom or ion in its ground state is called Ionization enthalpy.

Ionization energy also called ionization enthalpy, is the energy change involved when one electron is removed from a gaseous atom or ion.

Now for the right answer to the above question:

  1. Option A is incorrect. nothing like electron gain enthalpy.
  2. Option B is correct. ionization enthalpy = ionization energy.
  3. C is not correct. not enthalpy change.
  4. D is not the correct answer. Not a relevant option.

KEY-POINTS…

You may please note these/this:

  • Ionization enthalpy = ionization energy.
  • Ionization enthalpy is the molar enthalpy change accompanying the removal of an electron from a gas phase atom or ion in its ground state.
