Electron affinity vs electronegativity

[Darren Nguyen 1F]

Is there a difference?

I believe they reference the same idea, but electron affinity is a measured value of the amount of energy released when an electron is added to an atom, while electronegativity is a chemical property calculated using electron affinity.

Electron affinity is the energy released when an electron is added, while electronegativity is the tendency of an atom to attract electrons towards itself in a molecule of a compound.

[kendal mccarthy]

Electronegativity is the strength of an atom to attract an electron in a compound
ex. in H2O oxygen has a electronegativity giving the oxygen a partial negative charge and the hydrogens a partial positive charge.
Electron affinity is the energy released when an electron is added to an atom
ex. Flourine has a high electron affinity because it needs one electron to fill it's octet and then it will be in a more favorable/stable form.

Electronegativity has the same trend as electron affinity. However, the mathematical definition of electronegativity is Ionization Energy + Electron Affinity divided by two. In other words, electronegativity is the average between ionization energy and electron affinity.
