However under high temperature and high pressure, krypton and xenon from covalent bonds with fluorine and oxygen.
Noble Gasses.
Yes, the outermost energy level of the atoms of the noble gases are filled, meaning that they have the maximum number of electrons. This is why noble gases are stable and unreactive. The atoms of reactive elements share or transfer electrons in order to fill their outermost energy levels, making them stable like the noble gases.
Most atoms of the noble gases have eight valence electrons, which corresponds to a full outer electron shell. This complete electron configuration makes noble gases highly stable and unreactive, as they do not need to gain, lose, or share electrons to achieve stability. As a result, noble gases typically do not form chemical bonds with other elements.
Noble gases
Atoms gain, lose or share electrons and try to attain noble gas configuration.
The noble gases already have their full set of valence electrons. They don't need to share or transfer any of their electrons with other molecules.
I don't think noble gasses have valence electrons. They are noble because all their shells are full which makes them not as reactive.

Noble gases have completely filled orbitals. They are stable and chemically inert (non-reactive). So generally they will not accept / gain / share electrons and they do not form compounds.
Inert gases have 8 valence electrons. This is why they are inert, they have a complete octet formed of electrons and are in their lowest energy configuration.
Noble Gas Configurations
This is the family of noble gases (group 18).
Helium has 2 valence electrons. All other noble gases have 8 valence electrons.
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2 valence electrons) and have stable electronic configuration.
