2 valence electrons
Helium is a noble gas. It is part of the group of gases known as noble gases which have low reactivity due to their full outer electron shells.
Helium is not included in the noble gases group because it does not exhibit the full range of characteristics typically associated with noble gases. While helium is chemically inert like noble gases, it has certain properties that set it apart, such as a lower boiling point and lack of electron shell completions like the other noble gases.
Helium has two electrons which means the "valence" orbital is full, this also means that helium is not highly reactive. All of the noble gases also have filled "valence" orbitals so helium acts more like a noble gas and is placed in that column.
Helium, neon, and argon are the three lightest members of the noble gases.

HELIUM,NEON,ARGON,KRYPTON,XENON and RADON are the noble gases
Yes, they are all noble gases.
