Neon is a noble gas because it has a complete octat and it is stable in its ground state.
It is the noble gas family or the group XVIII.
xenon
Atoms gain stable configuration of noble gas, by either gaining or losing (as in ionic compounds) or sharing electrons (as in covalent compounds).
Because the outer electron shells are full.
For example, xenon, a noble gas can form stable compounds.
Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration.

Yes helium is a noble gas because it is very stable, colorless, odorless taste less, but unlike the other noble gases, it has two electrons in its valence shell.
Noble gases have a stable electron configuration. So they are less reactive.
There are three different ways for this. Elements can either gain electrons or lose electrons or share electrons and attain a stable noble gas electronic configuration.
Because the outer electron shells are full.
Full form: 1s1. it doesn't have noble gas configuration as there is no noble gas before hydrogen
