Why are noble gases stable?

The Noble Gas elements are stable and unreactive (inert) because the outer valence shells are complete with eight electrons, #s^2 p^6#

Neon - Ne #1s^2 2s^2 2p^6#
Argon - Ar #1s^2 2s^2 2p^6 3s^2 3p^6#
Krypton - Kr #[Ar] 3d^10 4s^2 4p^6#

With the outer s and p orbitals filled and the rule of octet satisfied the Noble Gas elements do not seek to gain or lose electrons through the process of bonding.
