So just to be sure, electronegativity follows the same trend as ionization energy and electron affinity on the periodic table right? If not, what trend does it follow?

Yes it does. They both refer to similar properties about an atom's electron-nucleus relationship.

yup! just remember that there are exceptions to electron affinity and ionization energy (N>O) rules.

Electronegativity is the ability of an atom to attract shared electrons toward itself. Electronegativity generally decreases down a group because there is more distance between the nucleus and the outer valence shell and increases across a period because the charge on the nucleus increases due to the increasing number of protons. Electronegativity relates to ionization energy and electron affinity.

Yes, you are correct. :) Electronegativity increases up and to the right of the periodic table.

Electronegativity does follow the same trend as ionization energy and electron affinity. Make sure to remember that there are a few exceptions to the ionization energy trend, but other than that these three properties all share the same trend (increasing across the period and decreasing down a group).

Electronegativity will increase moving up the periodic table, and also increase going from left to right each period!

Yes, ionization and electronegativity of atoms follow the same periodic trends. Remember however that there are exceptions to ionization trends.

I know that the trend of electronegativity increases as you go up and to the right, however, in the case of oxygen and chlorine which one has a higher electronegativity and what aspect of that element makes it so?

Yes! Also recall ionization energy is the energy need to remove a valence electron, and electron affinity is the energy released when an electron is bound to a neutral atom in gas phase.
