Helium (it has only 2 electrons, not 8).
Chlorine ion is more stable because it has got the maximum number(8) of electrons possible in its valence shell, it is known as the octet. When an ion achieves octet, it has got the electronic configuration of a noble gas, which is inert and very stable.
Atoms with a complete outer energy level or stable octet are more stable and less likely to react with other atoms. Inert gases like helium, neon, and argon have full outer energy levels and do not readily react with other elements, making them chemically stable.
When an electron has 8 electrons in its outer shell, it is considered to have a stable configuration known as an octet. This stable configuration is achieved by filling the outermost energy level with 8 electrons, following the octet rule.
Neon is called a noble gas because it is very unreactive due to its stable electron configuration, like the noble gases in Group 18 of the periodic table. It rarely forms compounds with other elements, making it "noble" or "inert" under normal conditions.

Helium (He) is a noble (inert) gas placed in the group 18 of the Periodic Table.Helium falls in inert gas. It is stable and non-reactive.
Noble gases have completely filled orbitals. Their valence orbitals are completely filled, have 8 electrons and obey octet rule (stable electronic configuration). They are chemically inert (or do not react with other elements).
Atoms with a complete outer energy level or stable octet are more stable and less likely to react with other atoms. Inert gases like helium, neon, and argon have full outer energy levels and do not readily react with other elements, making them chemically stable.
The noble gases have completely filled orbitals and are hence generally stable and chemically inert. The halogens need one more electron to complete octet and are generally highly reactive.
No, xenon cannot expand its octet because it is a noble gas with a stable electronic configuration of eight valence electrons.

They are generally stable as they obey octet rule
Radon is not the most inert gas in the atmosphere. Radon is a radioactive gas and is chemically inert, but it is relatively rare in the atmosphere compared to the noble gases like helium, neon, argon, krypton, and xenon, which are considered the most inert due to their stable electron configurations.
Argon has completely filled orbitals, satisfies octet rule and is chemically inert. So argon gas cannot harm human body.
