Noble gases have a full shell of valence electrons, therefore are unlikely to gain or lose any since they are stable.
Yes they do, because, for example, neon has 2 electrons in its inner shell and 8 on its outer shell; these shells are both full. Helium, the lightest of the noble gases, has only 2 electrons, but that completes it only shell. All the other noble gases have 8 electrons in their outer shell, which is a stable arrangement.
The inertness of noble gases is due to their complete outer electron shell configuration, making them stable and unreactive. This full shell makes it difficult for noble gases to gain or lose electrons, which are the key mechanisms for chemical reactions to occur.
Noble gases
Helium has a unique electron arrangement compared to other noble gases because it has only two electrons, filling its first energy level and forming a stable duet. In contrast, other noble gases, such as neon and argon, have full outer electron shells with eight electrons, following the octet rule. This difference in electron configuration contributes to helium's distinct properties, such as its smaller atomic size and lower reactivity compared to the heavier noble gases.
Noble gases are non polar like all other elements.

Noble Gas Configurations
This is the family of noble gases (group 18).
Helium has 2 valence electrons. All other noble gases have 8 valence electrons.
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2 valence electrons) and have stable electronic configuration.
Group 18 contains eight valence electrons, namely the noble gases.
Helium has only two valence electrons. All other noble gases have 8 valence electrons.
Helium has only 2 valence electrons. The rest noble gases have eight.
Bohr diagrams of noble gases show a full outer energy level with 8 electrons (except helium, which has 2 electrons). This configuration makes noble gases stable and less likely to react with other elements, giving them their "inert" or non-reactive properties.
