Well, electronegativity is conceived to be the ability of an atom involved in a chemical bond to polarize electron density towards itself...

Explanation:

[See this old answer and elsewhere.](https://socratic.org/questions/59d1966611ef6b327c46f564)

On the other hand, ionization energy can be directly measured...and is the energy associated with the formation of one mole of gaseous cations and electrons from one mole of gaseous atoms.

#M(g)+Delta_"ionization energy"rarrM^(+)(g) + e^(-)#

Discounting the Noble gases, the more electronegative an element, the GREATER should be its ionization energy.
