which best describes ionization energy?\nenergy needed to add an electron to a neutral atom in the gas phase\nenergy needed to add an electron to a neutral atom in the liquid phase\nenergy needed to remove an electron from an atom or ion in the gas phase\nenergy needed to remove an electron from an atom or ion in the liquid phase

Answer

Brief Explanations:

Ionization energy is defined as the energy required to remove an electron from an atom or ion in the gas - phase. Adding an electron is related to electron - affinity, and the liquid - phase is not relevant to the definition of ionization energy.

Answer:

energy needed to remove an electron from an atom or ion in the gas phase
