The noble gases: Helium, neon, etc.
It is a mixture of helium and neon gases.
That should be the first two noble gases: Helium and Neon. These two are chemically inert and do not react with anything.
The noble gas Neon is in neon signs.
helium, neon, argon, krypton, xenon and radon
helium is used for excitation of neon atoms in helium neon laser..
The salts in Fluorine are called fluorides, and fluorine reacts with all other elements except oxygen, neon, helium, and krypton.

because the size of helium is smaller than that of neon.
The noble gas Neon is in neon signs.
neon
helium, neon, argon, krypton, xenon and radon
Neon's mass is the element closest to 30 out of all noble gasses.
Helium is chemically inert and does not react with zinc
