Elements of the group 18 of periodic table, known as noble gases are the least reactive family of elements. The six naturally occurring elements in this group are helium, neon, argon, krypton, xenon and radon. The valence shells of them are completely filled so, they do not react easily with other atoms and mostly present as mono atomic gases. But with an exception of neon all elements can form stable compounds at least in theory!

Those would be the noble gasses. In the periodic system, this is the column on the far right. It contains elements like helium and argon.
