See explanation below.
Work Step by Step
The definition of electronegativity can best be defined as a value related with an atoms ability to form a covalent bond.
Electron affinity is the amount of energy that is released when an electron attaches itself to an atom.
Electronegativity really can't be measured and needs to be formulated from other atomic standards by differing equations.
Electronegativity values will vary with different chemical environments.
Electron Affinity is a value associated with atoms.
