If electronegativity is a function of ionization energy and electron affinity, how is it that there are no units associated with these values?

I thought it was because it electronegativies are just relative to one another.

I think it is because electronegativity is the tendency of atoms to attract a bonding pair of electrons, and is calculated, not experimentally measured

Electronegativity is calculated by using both electron affinity and ionization energy, so it is not a value that is calculated from an experiment. Since it is not a measured quality, it does not have units. Hope this helps!

The answer that you seek can be found here, they essentially divide the energy by a constant with the appropriate units to ensure that the resulting electronegativity is a dimensionless quantity
