Electronegativity and Electron Affinity.
What is the difference between electronegativity and electron affinity? I know that they both relate to attracting electrons, but is there a clear-cut difference between the two?
Re: Electronegativity and Electron Affinity. [ENDORSED]
Electron Affinity is the energy change when a neutral atom attracts an electron to become a negative ion.
Whereas, electronegativity is the ability of an atom to draw bonding electrons too itself.
They aren't too different. It is just that electron affinity is a fixed value of a specific atom while electronegativity is associated with molecules rather than a single atom.
Also, electron affinity values stay the same whereas electronegativity values can vary slightly with changing chemical environment.

This is answer is 99% correct... I might append that electronegativity is also defined for single atoms, it's just that in practice we normally only apply it to the qualitative prediction of electron densities in molecules

Re: Electronegativity and Electron Affinity.
Could anyone please remind me what the periodic trend is for electronegativity?
I was also wondering what the difference between electronegativity and ionization energy is?
Thank you so much
