Helium is the noble gas least likely to form a compound with another element because it has a full outer electron shell, making it very stable and unreactive.
Noble gas atoms have a full valence shell of electrons, making them highly stable. This stability reduces the tendency for noble gases to form bonds with other atoms. Additionally, noble gas atoms have a low electronegativity, making it difficult for them to attract or share electrons with other atoms to form bonds.
It is the noble gas family or the group XVIII.
Noble gases' atoms have the least tendency to form ions.
Nitrogen could achieve a noble gas configuration by gaining three electrons to form a stable octet, similar to the electron configuration of a noble gas such as neon. Alternatively, it could form nitrogen gas molecules (N2) through a triple covalent bond, which also results in a stable configuration with a full outer shell.
For example, xenon, a noble gas can form stable compounds.
The most stable cation in chemistry is the noble gas cation, which is formed when a noble gas atom loses an electron to become positively charged.
Helium is the noble gas least likely to form a compound with another element because it has a full outer electron shell, making it very stable and unreactive.
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.

Chlorine is most likely to form the monatomic ion Cl- (chloride ion) by gaining one electron to achieve a stable electron configuration similar to that of a noble gas.
Neither, Neon is an extremely stable noble gas.
Krypton is the noble gas most likely to form a compound with fluorine, typically by reacting to form krypton difluoride (KrF2).
Neon is a noble gas, and therefore, almost never is part of a compound.
