The noble gas group, also known as Group 18 or Group VIIIA, includes the following elements:

* Helium (He)

* Neon (Ne)

* Argon (Ar)

* Krypton (Kr)

* Xenon (Xe)

* Radon (Rn)

These elements are all colorless, odorless, and tasteless gases at room temperature. They are also very unreactive, due to their full outer electron shell, making them difficult to form chemical bonds.
