This is an oddly stated question but I would assume you are talking about elements such as neon, argon, xenon, krypton, i.e. noble gases which are monoatomic elements. They are inert gases that, under ordinary circumstances, do not react with other elements to form compounds.
Yes, argon is one of the noble gases which can be used for fluorescent lights.
Not normally.
argon
Helium, neon, argon, krypton, xenon and radon
yes
noble gases like helium, neon, argon
Neon and argon are two distinct elements.
Inert elements do not form bond.. Helium , neon and argon aren't likely to form bond.
neon diffuses 1.4 times as fast as argon.
The chemical symbols of neon and argon are Ne and Ar.
noble gases
Diffusion
Both neon and argon are stable because they have completely filled orbitals.
