Fluorine is a pale yellow gas and very reactive.
Chlorine is a pale green - which could look yellow depending on the lighting. it too is highly reactive.
Of the two, you would probably be looking for fluorine as the best answer.
Chlorine . The name comes the Classical Greek for Green , Chloros. We also have the word ' chlorphyll' for a green organic chemical .
Fluorine is a chemical substance - a halogen.
The purpose of halogen gas in a tungsten-halogen lamp is to increase the lifespan and efficiency of the lamp. The halogen gas helps to recycle evaporated tungsten back onto the filament, preventing blackening of the glass and extending the life of the lamp.
No halogen gas has a mass of under 15 atomic mass units. The closest is fluorine, at 19.0 atomic mass units.
Chlorine is classified as a halogen element in the periodic table due to its properties and behavior. It is a highly reactive, greenish-yellow gas under standard conditions and is commonly used in disinfectants, bleaches, and as a key component in the production of PVC plastics.
The halogen gas with a mass less than 15 is fluorine (F). It has an atomic mass of approximately 19.00 u, but if considering only the halogen gases, it is the lightest halogen. Fluorine is a pale yellow gas at room temperature and is highly reactive, particularly with alkali and alkaline earth metals.

Halogen gas is in a Tungsten-Halogen Light Bulb.
Halogen.
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.
Fluorine is a chemical substance - a halogen.
Argon is a noble gas. It is not a halogen. Fluorine is a example for that.
The purpose of halogen gas in a tungsten-halogen lamp is to increase the lifespan and efficiency of the lamp. The halogen gas helps to recycle evaporated tungsten back onto the filament, preventing blackening of the glass and extending the life of the lamp.
No halogen gas has a mass of under 15 atomic mass units. The closest is fluorine, at 19.0 atomic mass units.
That'd be Halogen.
Iodine is the halogen that sublimes directly from a solid to a gas at standard pressure and temperature.
If you mean the name of the element with the symbol F, it is Flourine
