Question

What is the basic difference between electron gain enthalpy and electronegtivity?

Answer 1

ELECTRONEGATIVITY: It is the ability of an atom to attract the shared or bonded pair of electrons.ELECTRON GAIN ENTHALPY: It is the energy change that occurs when an electron is added to the outermost shell of a 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.
