Ionization energy and electronegativity

What is the relationship between ionization energy and electronegativity? Are they like the same thing or what differentiates them? Also, what are the periodic trends associated with these terms again?

Electronegativity is a measurement of a neutral atom's likelihood of gaining an electron.
Ionization energy is the minimum energy required to remove a valence electron.
Both of these have the trend of increasing going towards the right and increasing going up the periodic table.

Ionization energy and electron negativity (and electron affinity and atomic radius) are involved in what an atom does to its electrons when it becomes bonded with another atom. They are two different things but they follow the same trend. Ionization energy is the energy required to remove an electron from an atom while electronegativity how strongly an element tends to pull shared electrons toward itself when it is in a bond. For ionization energy, as you go left to right on the periodic table ionization energy increases, and as you go top to bottom on the periodic table, ionization energy decreases. For electronegativity, as you go left to right on the periodic table electronegativity increases, and as you go top to bottom on the periodic table, electronegativity decreases.

Both ionization energy and electronegativity are related with ionization energy referring to how much energy is needed to remove an electron, while electronegativity refers to the relative strength of the pull of shared electrons unequally within a bond.

It might also be helpful to know that electronegativity refers to an atom's electron pulling power when bonded with another atom. For ionization energy, it is just the energy required to remove an electron from the single atom itself.

Hope this helps to distinguish the two!

electronegativity is usually a combination of ionization energy and electron affinity. That's why they usually have the same periodic trends.

Would the ionization and electronegativity trend be the same on the periodic table?

Yes. The trends for ionization energy, electron affinity and electronegativity are the same.

The trends for ionization energy and electronegativity in the periodic table increase across a period and down a group. Ionization energy is the energy it takes to remove a valence electron from an atom. Electronegativity measures how much the atom is able to attract electrons.
