Do noble gases have electron affinity?
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 don't the noble gases have an electron affinity value?
Noble gases have a full valence shell of electrons, so they are stable and do not readily gain or lose electrons. This stability leads to very low electron affinity values for noble gases, as they do not have a strong tendency to attract additional electrons to achieve a more stable electron configuration.
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 group of elements give off the most energy when they gain an electrons?
Group 8A, the noble gases because they have high electron affinity.
Why the helium is not included in noble gases group?
Helium is not included in the noble gases group because it does not exhibit the full range of characteristics typically associated with noble gases. While helium is chemically inert like noble gases, it has certain properties that set it apart, such as a lower boiling point and lack of electron shell completions like the other noble gases.

Why are electron affinity values for the noble gases endothermic?
Electron affinity values for noble gases are endothermic because these elements have stable electron configurations and do not readily accept additional electrons. This makes it energetically unfavorable for them to gain an extra electron, resulting in a positive electron affinity value.
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.

This stability leads to very low electron affinity values for noble gases, as they do not have a strong tendency to attract additional electrons to achieve a more stable electron configuration.

Which element would most likely have a positive electron affinity between Na Al Rb and Ar?
Chlorine (Cl) would most likely have a positive electron affinity. Typically, elements with high electron affinities are found on the right side of the periodic table, closer to the noble gases. Among the choices given, Argon (Ar) is a noble gas and has a positive electron affinity.
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.

Helium is not included in the noble gases group because it does not exhibit the full range of characteristics typically associated with noble gases. While helium is chemically inert like noble gases, it has certain properties that set it apart, such as a lower boiling point and lack of electron shell completions like the other noble gases.
Why are the noble gases non reactant?
Noble gases have atoms with the valence electron shell filled.
What do halogens and noble gases have very different chemical properties?
Halogens are highly reactive due to their tendency to gain an electron to achieve a stable electron configuration, while noble gases are already stable and do not readily react with other elements. Halogens are typically electronegative, whereas noble gases have very low electronegativity. This difference in reactivity and electron affinity leads to halogens forming compounds easily, while noble gases tend to exist as isolated atoms.
What is the electron affinity value and which elements have a zero value?
Electron affinity is the energy released when an electron is added to a neutral atom. Elements with a zero electron affinity value include neon, helium, and argon because they have stable electron configurations and do not readily accept additional electrons.
What is the electron configuration for noble gases?
