Want this question answered?
helium He, neon Ne, argon Ar, krypton Kr, xenon Xe. I think this is all of the ones used for lighting if not please add any others.
Noble(nonreactive) gases like argon
To produce something that can be uses
argon or noble gases
An inert noble gas is used inside light bulbs.
Whoever came up with this question didn't understand the material. The answer is probably supposed to be "helium and neon."

Krypton (Kr) is a noble gas found in the air. It has limited its practical applications, but never the less, Krypton is used in some types of photographic flashes used in high speed photography. Some fluorescent light bulbs are also filled with a mixture of krypton and argon gases. Krypton gas is also combined with other gases to make luminous signs that glow with a greenish-yellow light.
No, there are a variety of instances where their inertness proves useful, such as incandescant light bulbs or in agitating molten iron without increasing iron oxide content
You're probably thinking of the kind of bulbs used in floodlights (streetlights or industrial lighting) which do not shed much light when they're first turned on, because they have to warm up. It can take several minutes for the bulbs to reach their nominal operating temperature and come to full brightness.
hydrogen is not used in bulbs it is usually argon or another noble gas. e.g neon
Neon, in the periodic table, is a noble gas, so it's extremely unreactive, colorless, and odorless. Neon lights emit light when electrons move through a gas or a mixture of gases inside glass tubing.
