Question

Electronegativity and electron gain enthalpy of noble gases are zero explain

Answer 1

Explanation:

Noble gases have zero electron gain enthalpy because they contain all paired electrons and there is no place to accept another electron. All the orbitals are completely filled in them. So, they can't accept an electron and so the enthalpy is zero.

Electronegativity is the ability of an atom to gain an electron. ... Since the noble gases already have eight electrons in their outer shells, they dont wan't to attract any more. Since electronegativity measures the amount of attraction between an atom and an electron, noble gases do not have electronegativity.

hope it helps.........

Answer 2

Explanation:

Noble gases are so stable that it is difficult to add a electron. So electron gain enthalpy or electron negativity of noble gases is 0.
