Electronegativity

[Drew Myers 4G]

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?

[AVerma_F19]

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

[John Liang 2I]

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

[JamieVu_2C]

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.

[Jesalynne 2F]

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

[MTanikella_1K]

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).

[CalvinTNguyen2D]

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

[ramiro_romero]

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

[Natalie Benitez 1E]

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?

[Tiffany_Chen 2K]

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.
