A full octet makes the noble gases nonreactive.
They're all Noble gases.
Group 17 elements are called halogens, which include fluorine, chlorine, bromine, iodine, and astatine. Group 18 elements are called noble gases, which include helium, neon, argon, krypton, xenon, and radon.
The family name of argon is the Noble gases.
its the noble gases that are the least reactive group among the elements; and they occupy the left most group i.e. 18th group in the Periodic Table.
Noble gases, such as helium, neon, and argon, do not typically form compounds because they have a stable electron configuration with a full outer shell of electrons, making them very unlikely to gain or lose electrons to form bonds with other elements.

The Noble Gases
A full octet, which refers to having eight electrons in the outermost shell, contributes to the stability of noble gases, making them largely inert and unreactive. This complete electron configuration results in low chemical reactivity compared to other elements, as noble gases have little tendency to gain, lose, or share electrons. Consequently, this stability influences trends among the noble gases, such as their increasing atomic size and boiling points down the group, as larger atoms have more electron shells while maintaining the full octet. Overall, the presence of a full octet is a key factor in the distinctive inertness and unique properties of noble gases.
helium has the least density, xenon has the highest.
Among the noble gases, radon has the largest size and hence will have the lowest ionisation energy
Alkali metals and noble gases
The group of noble gases (Group 18) does not follow the normal trends seen in other groups on the periodic table. This is because they have full outer electron shells, making them very stable and unreactive compared to other elements.
Noble gases exist in nature in very low concentration and are very unreactive. These prevented their discovery earlier.
Noble gases are chemically inert, they do not form compounds. They are found in trace amounts and hence difficult to be identified.
Radon has the largest atomic radius among the noble gases due to the increased number of electron shells, causing the atoms to be larger in size.
