The elements helium, copper, neon and argon are commonly referred to as noble gases. These are mainly obtained from air in an air separation unit.

Helium, Neon, Argon, Krypton, Xenon, and Radon.helium (studyisland answer)
helium, neon, argon, krypton, xenon and radon
Inert elements do not form bond.. Helium , neon and argon aren't likely to form bond.
helium, neon, argon, krypton, xenon, radon, ununoctium
Helium, argon, and neon are noble gases, so the only "reactive" element of the four is hydrogen.
Neon, argon, and oxygen are all different elements. They are not synonymous in any way.
Helium, Neon, Argon, Krypton, Xenon, and Radon
They are 'inert' elements, and gases too.
Helium, neon, argon, krypton and xenon.
