Because it's reactivity is closest to that group.
HELIUM,NEON,ARGON,KRYPTON,XENON and RADON are the noble gases
Yes, they are all noble gases.
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 is grouped with the elements of group 8 (noble gases) because it has a full outer electron shell, making it chemically stable and unreactive just like other noble gases. It follows the octet rule, having 2 electrons in its outer shell, similar to the other group 8 elements.
They're all Noble gases.
Helium, neon, and argon are the three lightest members of the noble gases.
There are no metals in noble gases.All are gases in noble gases.
