electronegativity and electron affinity

Postby 405404782 Gabriel Rigole 4F » Sun Nov 03, 2019 6:12 pm

Can someone please explain the difference between electronegativity and electron affinity?

Electron affinity is a measured value, of the energy released when the element in its gaseous state gains an electron. Electronegativity is a calculated value denoting how well something attracts electrons

Electronegativity is the tendency of an atom to attract electrons to itself. Electron affinity is the amount of energy required when an electron is added to an atom or molecule in its gaseous state to form a negative ion. Hope this helps.

Electronegativity is a measures how strongly atoms attract bonding electrons to themselves, whereas electron affinity is the amount of energy released or spent when an electron is added to a neutral atom or molecule.

Electron affinity and electronegativity are related in that elements with high electron affinities and high ionization energies have high electronegativities. However, electronegativity refers to the electron-pulling power of an atom when it is part of a molecule. Electron affinity refers to a neutral atom's likelihood of gaining an electron. Therefore, though separate measures, the calculation and determination of electronegativity values depends on electron affinity, as electrons that have a high likelihood of gaining an electron will also have a stronger electron-pulling power.
