Question

distinguish between electron gain enthalpy and electronegativity
​

Answer 1

Answer:

An electron is a subatomic particle of an atom. Electrons are found everywhere since every matter is made up of atoms. However, electrons are very important in some chemical reactions since the exchange of electrons is the only difference between reactants and products in these reactions. Electron gain enthalpy and electronegativity are two chemical terms used to explain the binding of an electron with an atom. Electron gain enthalpy is the amount of energy released by an atom when an electron is gained from outside. Electronegativity is the ability of an atom to gain electrons from outside. Hence, electron gain enthalpy quantifies the electronegativity. The main difference between electron gain enthalpy and electronegativity is that electron gain enthalpy is measured by kJ/mol unit whereas electronegativity is unit-less and is measured by Pauling scale.
