The valence electron shell of noble gases id completely filled; as a consequence the affinity for electrons and the chemical reactivity are at an extremely low level.

Why are the noble gases not included in electron affinity?
Noble gases have completely filled orbitals are are stable. they do not accept electrons and hence are not included in electron affinity.
Why don't the noble gases have an electron affinity value?
they dont want any electrons cuz they got no room to put them
What group of elements give off the most energy when they gain an electrons?
Group 8A, the noble gases because they have high electron affinity.
What is the electron affinity value and which elements have a zero value?
Noble gasses
Why the value of electron affinity is positive for noble gases?
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. They will not accept any more electrons and hence they have positive electron affinity.

What is the electron affinity of argon?
The electron affinity of argon, like all noble gases, is 0, or very close to it, due to its chemical inertness.

Why are the noble gases non reactant?
Noble gases have atoms with the valence electron shell filled.
What is it called when an electron has 8 electrons in its outer shell?
when an element has 8 electron in outer shell it is said to be inert. inert gases are called noble gases.
What is the electron configuration for noble gases?
[noble gas]ns2 np6
Definition of electron affinity?
The energy change that occurs when an electron is added to a neutral atom. This is usually exothermic. Noble Gases are excluded from this. Equation: X(element)+e-(electron)---------> X-1+ energy
What energy changes when a neutral atom gains an electron?
When an electron is acquired by a neutral atom, the energy change is called electron affinity. Neutral atoms with an s2p6 electron configuration in the highest energy level are best classified as gases.
Are noble gases diatomic?
Noble gases have full outer electron shells, thus have no 'desire' to combine with anything, even its "brothers."Noble Gases are not diatomic.
