Helium, neon, and argon are examples of
neon
Column 18.
They are the noble gasses helium, neon, argon, krypton, xenon and radon and also less importantly the highly unstable and virtually non existent in nature: ununoctium. These noble gases have stable electronic configuration (they have completely filled valence orbitals / energy levels) and are chemically inert under STP. Hence they are considered to be inert gases.
because helium , neon n argon have a completely filled outer shell n thus require no extra electrons. this is also the reason why they were discovered so late.
Helium, neon, krypton, xenon, radon and ununoctium.
Helium,neon,argon
helium, neon, argon, krypton, xenon and radon are the six noble gases.
helium, neon, argon, krypton, xenon and radon
neon
Helium, neon, and argon are the three lightest members of the noble gases.
The five noble gasses are neon, xenon, kryton, helium, argon, radon, and ununoctium.

We know helium, neon, argon, krypton, xenon and radon as the inert or noble gases. You probably don't need examples since there are only six of these elements. Why not just list them all?
The first four are (in order of increasing number / mass: He = Helium, Ne = Neon, Ar = Argon, Kr = Krypton Xe = Xenon and Ra = Radon are the other two noble gases
Examples are helium, neon, argon.
