Answer:

See below.

Explanation:

Ionization energy is the energy needed to remove an electron from an atom or an ion at its gaseous state.

Electron affinity is the energy released or absorbed when an electron is added to an atom or ion at its gaseous state.

I just made two videos on these topics recently, I hope you find them helpful:
