Halogen is a gas, so your question doesn't make much sense.
If you're asking about a halogen (light) bulb, then the answer is: mainly halogen.
Halogen gas is in a Tungsten-Halogen Light Bulb.
No, it is a noble gas
Iodine is a non-metal. It belongs to group 17 (halogen family).
Noble gases are, for all intents and purposes, unreactive - there are a few noble gas compounds but you have to really work at it to convince noble gases to form bonds. Fluorine is an extremely reactive gas, hence it is not a noble gas. It is a halogen - the most reactive halogen of them all.
Fluorine, at 19 atomic mass units, is the only halogen gas that fits that requirement.

Halogen.
Argon is a noble gas. It is not a halogen. Fluorine is a example for that.
That'd be Halogen.

Chlorine is a halogen.

No, it is a noble gas
A halogen bulb is a traditional tungsten filament bulb filled with a noble gas that gives off a soft, yellowish light. In a metal halide bulb, the light emitted is bright white or even bluish. They have a longer life than halogen bulbs, but their brightness can diminish over time.
Iodine is a non-metal. It belongs to group 17 (halogen family).
