Atoms or molecules do chemical reactions to be stable, noble gasses are already stable, so they do not react with other molecules to form chemical bonds
Noble gases
noble gases are already stable.
The noble gases. For example: Helium, Neon, Argon etc
Noble gases already have a full valence shell.
Noble gases do not usually form chemical bonds.
Noble gases have completely filled electronic configuration and hence they are chemically inert (they generally do not form bonds).
They have a full octet of electrons
Metals form cations by the complete transfer of electrons. Metalloids and some noble gases generally form covalent bonds
They are gases that do not form normal chemical bonds with more than a very few other elements.
VIII group or the noble gases
Because they lack valance electrons
they have a full outermost energy level.
