Both have the same trend on the periodic table, but what is the difference between the two?

Ionization energy: the energy required to remove an electron from a neutral atom.
Electronegativity: the ability of an atom in a molecule to draw bonding electrons to itself.

The main difference is that electron affinity gives the amount of energy released when an atom gains an electron while ionization energy is the amount of energy required to remove an electron from an atom.

Ionization energy is the amount of energy you need to remove an electron from an atom/ion while electronegativity is how likely an atom is to gain/attract an electron.

Just keep in mind that the ionzation energy trend is not exactly the same as the electronegativity trend because for ionization energy there is an exception when it comes to Nitrogen and Oxygen. For the most part, ionization energy does increase going up and across to the right of the periodic table but for oxygen, the Ionization energy drops so Nitrogen would have higher ionization energy than oxygen.
