inert gases ..like nitrogen or argon
inert gas
Tungsten is an element often found in cheaper light bulbs.
Argon is an element that is a gas at room temperature. It can be found in incandescent light bulbs because it is inert.
Argon gas .
Assuming the question is referring to incandescent light bulbs (the ones with the glowing filament), Argon is the gas used.Argon is a harmless gas found in air, and is used because it cannot react with the hot filament.
An energy saving light bulb is simply a fluorescent light-bulb in a small housing with a built in starter . The gas used for it will be the same as a standard strip-light which is a tube filled with low pressure mercuric oxide and an inert gas like Argon Neon or krypton.
Argon. As an inert gas, it makes the filament last longer. Some light bulbs also use Krypton.
Argon (Ar)
Argon
Argon and/or nitrogen.
There is argon in light bulbs so the filiment doesn't does combust. However the gas doesn't come out of the bulb unless you break it.
An inert noble gas is used inside light bulbs.
