noble gasses
The Noble Gases.
The so-called noble or inert gases are in Group 18, the last group on the right of the periodic table of the elements.
I - Alkali Metals II - Earth Alkali Metals III - Boron Group IV - Carbon Group V - Nitrogen Group VI - Chalcogenes VII - Halogenes VIII - Noble Gases
Helium is a Noble Gas in Group O.
Groups are made according to the properties of elements. Noble gasses have similar properties. So they comes in the same group.
This is the family of noble gases (group 18).
