What is the relation of electronegativity with ionization energy and electron affinity? It seems like they have similar trends on the periodic table, but it would be helpful if someone could help explain how?

Ionization energy is the energy required for an atom to lose an electron; electron affinity is the energy released when an atom gains an electron.

Electronegativity is calculated from the measured ionization energy and electron affinity, which is why they all have similar trends. As ionization energy and electron affinity increase, so will electronegativity because it is a product of these two measurements

Electronegativity is the measure of the attraction of electrons to a certain atom. Therefore, electronegativity influences both electron affinity, the energy released when an electron is added to an atom, and ionization energy, the energy requires to remove an electron.
