The region of the periodic table that contains the stable, unreactive noble gases is Group 18, also known as Group VIIIA.

These elements are known as noble gases because they are extremely unreactive due to their full outer electron shells. They have a stable electron configuration, meaning they don't readily gain or lose electrons to form chemical bonds.

Here are the elements in Group 18:

* Helium (He)

* Neon (Ne)

* Argon (Ar)

* Krypton (Kr)

* Xenon (Xe)

* Radon (Rn)

While historically these elements were called "inert gases," we now know that some of them can form compounds under specific conditions. However, they are still generally considered unreactive.
