difference between electronegativity and electron enthalpy
Answers
Explanation:
Electronegativity measures the ability of an atom to gain an electron from outside. 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.
Explanation:
Electronegativity is a the tendency of an atom to attract the lone pair in bond towards itself.
It is a hypothetical
It is like temperature. Does temperature exist? It is just an indirect way to measure the kinetic energy of a system. But kinetic energy is measured in joules.
Electron gain enthalpy is defined as the energy released/absorbed by an isolated gaseous atom when an electron is brought inside it.
Electron affinity is the amount of energy gain or lost by the surrounding of an isolated gaseous atom when an electron is brought inside it..
The greater the negative value of electron gain enthalpy, the greater the stability of the atom. The greater the positive value of electron affinity, the greater the stability of the atom.
Electron gain enthalpy = -(electron affinity)
