Question

What is the basic difference between electron gain enthalpy and electro negativity?

Answer 1

Electronegativity is the tendency to pull the pair of electrons towards it (about whose EN we are speaking about)

Electron gain enthalpy is the amount of energy liberated when an electron is added to valence shell of neutral gaseous atom

Answer 2

Explanation:

Electron gain enthalpy is the tendency of an isolated gaseous atom to accept an extra electron to form a gaseous anion while electronegativity is the tendency of an atom of an element to attract the shared pair of electrons towards itself in a covalent bond. Unlike electron gain enthalpy, electronegativity is not a measurable quantity.
