Question

Difference between Electron gain enthalpy and Electronegativity.

Answer 1

Electron gain enthalpy	Electronegativity
Tendency of an isolated gaseous atom to attract an electron.	Tendency of an atom to attract shared pair of electrons in a bond.
Can be measured experimentally.	Cannot be measured experimentally.
Property of an isolated atom.	Property of bonded atom.
It is constant.	It is not constant. It depends on the hybridization of atom and nature of other bonded atom
