Ionization energy is the energy required to remove an electron from a gaseous atom while electron affinity is the energy released when an electron is added to a gaseous atom.

They have the same trend on the table too, increase as you go from left to right and decrease as you go from top to bottom.

Ionization energy is the energy required to remove an electron from an atom, whereas electron affinity is the energy involved when an electron adds to an atom.

The difference between the two is exemplified below:
Ca → Ca⁺ + e⁻ [Ionization Energy]

Ca + e⁻ →Ca⁻ [Electron Affinity]
