However under high temperature and high pressure, krypton and xenon from covalent bonds with fluorine and oxygen.
No they dont. noble gases have completely filled orbitals, are stable and hence they do not form ions.
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.
Noble Gasses.
Noble gases
The noble gases are always found pure because they already have their full set of valence electrons. They don't need to share or transfer any of their electrons with the other molecules.
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.
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.

Group 18 contains eight valence electrons, namely the noble gases.
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.
Atoms gain, lose or share electrons and try to attain noble gas configuration.
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.
Noble Gas Configurations
Helium has 2 valence electrons. All other noble gases have 8 valence electrons.
