group 18
Helium, neon, argon, krypton, xenon and radon all belong to group 18.
Firstly, helium does NOT belong to group 8. In the periodic table used until around the 1960s, helium belonged to group zero. Iron cobalt, and nickel families shared group VIII. In the modern, iupac sanctioned periodic table, the noble gas family -- helium, neon, etc. -- are in group 18. I think the reason your teacher (? or textbook, or whoever) has asked this question is because all of the other noble gases have 8 electrons in their outermost shell, while helium has only 2.
Helium is the element that doesn't belong in a group with any others on the periodic table. It is part of Group 18, the noble gases, which are characterized by their stable and unreactive nature.
Argon and Helium are part of the noble gasses family.
hydrogen is in group 1, the rest in noble gases (group 18)
noble gases or group 18
Helium is a gas, belonging to noble gases (group 18)
Noble gases. Also known as Group Zero and inert gases.
Helium, neon, argon, krypton, xenon and radon all belong to group 18.

Argon and Helium are part of the noble gasses family.
The noble gas group contain: helium, neon, argon, krypton, xenon, radon, Uuo.
hydrogen is in group 1, the rest in noble gases (group 18)
All of these elements belong to the noble gas family or group 18 on the modern periodic table
Helium belongs in the noble gas family, which is group 18 (VIIIA or 0) on the periodic table. It is a noble gas because its valence shell is filled (with two electrons) and it is completely non-reactive.
Helium is not a group. It is an element.
