Helium belongs to the 18th group which is known as noble gases/rare gases/zero group elements/inert gases.
The other member are
- Neon(Ne)
- Argon(Ar)
- Krypton(Kr)
- Xenon(Xe)
- Radon(Rn)
There is a vacant space at 118 i.e.marked as Un-Un Octium (Uuo) in the Periodic Table. If any element occurs that place, then it will be a rare gas.
