Electronegativity
What happens to the electronegativity of an atom that has high ionization energy and high electron affinity? What happens to the electronegativity of an atom that has low ionization energy and low electron affinity? Also, what is the pull like on the electrons on both atoms?

Re: Electronegativity
The electronegativity of an atom with high ionization energy and electron affinity is going to pretty high. This is because the atom would be more stable with more electrons, so it's a very plausible state for the atom. The opposite is true for an atom with low ionization energy and electron affinity, which would have a low electronegativity. These atoms are more likely to get rid of an electron rather than gain one.

Re: Electronegativity
Higher ionization energy and electron affinity makes for higher electronegativity, and vice versa for low IE and EA. I'm not sure what you mean by the pull of electrons because electronegativity refers to single atoms, but higher electronegativity means that the atom can 'pull' electrons better.

Re: Electronegativity
Electronegativity is a calculated value from the measured values of ionization energy (IE) and electron affinity, therefore it follows the trend of IE and electron affinity. Both IE and electron affinity increase across a period and up a group. Thus, electronegativity is also high, so the atom pulls shared electrons toward it, creating a partial negative charge on the atom. When IE and electron affinity are both low (bottom left of PT), electronegativity is also low, so the atom doesn't pull shared electrons very close to it, thus creating a partial positive charge on the atom.

Re: Electronegativity
High ionization energy and high electron affinity leads to electronegativity and low ionization energy and electron affinity leads to low electronegativity. The pull between the atoms is a slight negative charge.

Re: Electronegativity
High ionization energy + high electron affinity --> high electronegativity
Low ionization energy + low electron affinity --> low electronegativity
Ionization energy refers to the amount of energy it takes for an element/molecule to lose an electron.
Electron affinity refers to the amount of energy an element/molecule releases with the addition of an electron.
Low ionization energy + low electron affinity --> low electronegativity
Ionization energy refers to the amount of energy it takes for an element/molecule to lose an electron.
Electron affinity refers to the amount of energy an element/molecule releases with the addition of an electron.

Re: Electronegativity
The First one will have high electronegativity. The second will have low electronegativity

Re: Electronegativity
An atom with high ionization energy and high electron affinity would have high electronegativity, and the opposite goes for atom with low ionization energy and low electron affinity.
Re: Electronegativity
An atom that has high electron density and ionization energy also has high electron affinity, and vice versa. Hope this helps!
