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

Neon - Ne $1 s^{2} 2 s^{2} 2 p^{6}$ $1s^2 2s^2 2p^6$
Argon - Ar $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6}$ $1s^2 2s^2 2p^6 3s^2 3p^6$
Krypton - Kr $[A r] 3 d^{10} 4 s^{2} 4 p^{6}$ $[Ar] 3d^10 4s^2 4p^6$

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.
