Helium is one of the six Noble Gases, along with Neon, Argon, Krypton, Xenon, and Radon.
Helium belongs to the family of the 'noble gases'
All of these elements belong to the noble gas family or group 18 on the modern periodic table
Group 7 of the periodic table.
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.
