Why is argon used in a light bulb instead of air?
Why is argon used for light bulbs?
Argon is an inert gas that will not support burning when the bulbs filament becomes white hot because of the current running through it. When a light bulb consists of tungsten…, when electricity is passed through it, tungsten offers a very high resistance and it becomes hot and produces white light. At this temperature when it is exposed to air, tungsten gets oxidized. So prevent its oxidation, tungsten is burnt in the atmosphere of argon, which is a inert gas.
How is argon used in the production of light bulbs?
Argon does not react. :)
Why are light bulbs filled with argon and not air?
If you use air instead of argon to fill a light bulb, the air will burn the light bulb.
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 use in a light bulb?
Because argon is an inert gas; the oxidation of the wolfram filament is not possible in pure argon.
Why is argon a good gas to use in light bulbs?
Argon is an inert gas that will not oxidize the filament even atextremely high tempt.
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.
Is argon used in a light bulb?
yes argon is used for light bulb and it is not reactive
Why do you use argon in a light bulb?
it's not very reactive
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 you use argon or nitrogen gas in light bulb?
Incandescent light bulbs traditionally use argon as the interior gas. The gas is inert, so it does not interfere with the glowing filament.

What property of argon is used in light bulbs?
Its chemical unreactivity. Argon, along with helium, neon, krypton, xenon and radon are the noble gases. Because their outer shells are completely filled with electrons, they …never react with any other atoms in nature. Therefore in a light bulb filled with argon the hot tungsten filament will not corrode as it would if air were present. Oxygen in the air would react with the hot tungsten, essentially rusting it and causing the bulb to fail. Xenon, krypton and possibly helium can be made to react only under extreme laboratory conditions. A chemist won the Nobel prize for doing this in the 1960's. But neon and argon have never been made to react at all. Argon is used in bulbs rather than the other noble gases because it is abundant and therefore inexpensive. Ordinary air is about 1% argon, 21% oxygen and 78% nitrogen. Argon can also be used to fill the air space in partially drunk bottles of wine. The wine will then not react with oxygen and go sour.

Why is argon used in light bulbs use electronic structure of the argon atom?
Argon is a noble gas meaning it can't chemically bond with anything else. Using air will instantly burn the filament. .
Also, argon has a full outer shell (8 electrons) meani…ng it is unreactive.
