Which of the following is not involved in Born-Haber cycle?

In the formation of NaCl, the Electron affinity of Cl is considered but not electro negativity (E.N).

$∆{\mathrm{H}}_{\mathrm{f}}=∆{\mathrm{H}}_{\mathrm{sub}}+\mathrm{I}.\mathrm{E}+∆{\mathrm{H}}_{\mathrm{diss}}+\mathrm{E}.\mathrm{A}+\mathrm{U}$

here $∆{\mathrm{H}}_{\mathrm{f}}=\mathrm{enthalphy} \mathrm{of} \mathrm{formation}.$

$∆{\mathrm{H}}_{\mathrm{sub}}=$Sublimation energy

$\mathrm{I}.\mathrm{E}=$Ionization energy

$∆{\mathrm{H}}_{\mathrm{diss}}=$Bond dissociation energy

$\mathrm{E}.\mathrm{A}=$Electro affinity

$\mathrm{U}=$Lattice energy

Note: To calculate the lattice energy through Born-Haber cycle there is requirement of electro negativity of the element
