The filament lasts for a long time because argon is inert and will not oxidize the filament even at high temperatures.

If air were used, the oxygen would quickly react with and destroy the hot filament within seconds of it being turned on.

Quick experiment: Attach a wire to the positive and negative sides of a large flashlight battery (the large rectangular ones with the two coils coming from the top... I can't think of the proper size). Attach the back of one alligator clip to the open end of each wire (so the clip part is not clipped on the wire). String out some steel wool until you have a single strand (or two or three wound together). This essentially is a light bulb filament. Clip it into the two alligator clips and watch how fast it burns.

Argon is often used when an inert atmosphere is needed. It is used in this way to protect the weld area and in incandescent light bulbs to stop oxygen from corroding the filament.

In a bulb noble gas argon is used . why is argon is used instead of air in the light bulb?

It won't burn the filament.


Is argon used in a light bulb?

yes argon is used for light bulb and it is not reactive


In a bulb a noble gas argon is used why is argon used instead of air in the light bulb?

Argon can be used in bulbs much like neon can; where neon gives off a reddish-orange light, argon is a bluish tint. If argon is used in an incandescent bulb it's probably to protect the filament from oxygen in the air. However, I'm not sure this is ever actually done; I know nitrogen is sometimes used for this purpose, but using argon seems to be overkill.


Why is argon used instead on air in the light bulb?

The filament in the light bulb is heated to a very high temperature. At such a temperature oxygen from the air would oxidise the metal(s) in the filament and thereby destroy the bulb. Using an inert gas such as argon in the bulb prevents such oxidation.


Can argon be put in a light bulb?

Yes and it is often used


Which gases are used in a light bulb?

argon and xenon i think


Which gas is used in light bulb?

regular light bulbs have argon and/or nitrogen


Why air is not filled in electric bulb?

If air were used in an electric bulb the filament, which becomes extremely hot when the light is on, would rapidly oxidize and burn out in seconds. Instead the bulb is filled with argon, which is inert.


Why is argon used in light bubs instead of vacuum?

argon is no reactive how ever vacuum


Can a light bulb work with just oxygen instead of argon?

No. Light bulb filaments become extremely hot when in use, and oxygen, which is highly reactive, would cause the filament to burn away in a matter of seconds. Argon is used because it is inert, and thus will not react with the filament.


Why was argon gas chosen for a light bulb?

Argon is often used when an inert atmosphere is needed. It is used in this way in incandescent light bulbs to stop oxygen from corroding the filament. Argon is used in fluorescent tubes and low-energy light bulbs. A low-energy light bulb often contains argon gas and mercury. When it is switched on an electric discharge passes through the gas, generating UV light. The coating on the inside surface of the bulb is activated by the UV light and it glows brightly.


Why is argon used insted of air in the light bulb?

because the oxygen in air would burn causing the light bulb to burn out very quickly.


Why are noble gases used in light bulbs?

Noble gases are used in light bulbs because of their properties. For example, argon prevents tungsten filaments from evaporating. Thus, argon increases the life of the light bulb.


This gas does not react at all It is used in light bulbs so that the metal in the light bulb can get very hot without burning?

Argon


What is the gas that does not react at all and it is used in light bulbs so the metal in the light bulb can get very hot without burning?

Argon


Is there air in a light bulb?

No. Not normal air. The oxygen in air would cause any light bulb to burn out in seconds. In stead, and inert gas called argon is used.


What elements are in a light bulb?

There are various elements that are found in a light bulb. Some of the elements include the filament, fill gas which is commonly mercury or argon and iodine which is used in halogen bulbs.


What are the common elements on the periodic table that are used in a light bulb?

There are numerous elements that are used in making a light bulb. Some of these elements are tungsten, mercury, argon, and various members of the element group known as halogens.


Why do they use argon gas in a light bulb?

It is used to replace oxygen so that the hot filament does not get oxidised or burn.


What is used in light bulbs so that the metal in the light bulb can get very hot with out burning?

Any inert gas, such as helium, argon or xenon
