Final answer:
Helium (He) is a noble gas, along with other elements like neon, argon, krypton, xenon, and radon. Noble gases are chemically inert and have full outer electron shells.
Step-by-step explanation:
The element helium (He) is a noble gas. Noble gases are a group of elements on the periodic table that are characterized by their low reactivity and full outer electron shell. These gases include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). They are called noble gases because their chemical behavior is noble or inert, meaning they do not easily react with other elements.
