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.
Fluorine is an element that is a halogen gas that is yellow and explosive.
Chlorine. Explosive with hydrogen, (not the ordinary definition of explosiveness)
There are two Halogens that are gasses at room temperature: fluorine and chlorine, they are not flammable but are oxidizers.

Chlorine . The name comes the Classical Greek for Green , Chloros. We also have the word ' chlorphyll' for a green organic chemical .
Chlorine is a halogen.

No. Argon is a noble gas.
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.
Argon is a noble gas. It is not a halogen. Fluorine is a example for that.
That'd be Halogen.

The halogen gas that is that most reactive of all elements is Fluorine
Chlorine . The name comes the Classical Greek for Green , Chloros. We also have the word ' chlorphyll' for a green organic chemical .
This gas is helium.
Chlorine is a halogen.
chlorine
No, it is a noble gas
