a) Electron gain enthalpy-It is the tendency of an atom to attract outside electrons.
It is the property of an isolated atom.It is the absolute electron attracting tendency of the atom
It has units like KJ/mol & Ev/atom
b) Electronegativity-It is the tendency of an atom to attract shared pair of electrons.It is the property of bonded atom.
It is the relative electron attracting tendency of an atom.It has no units
