Light in a lightbulb is produced by running a current through a wire with a high resistance. This creates a lot of heat, which when hot enough creates light. Imagine heating up a piece of steel until it glows.
If the bulb was filled with oxygen, the tungsten filament would burn before it ever got to hot enough temperatures for our light needs. Therefore, we use argon so that while it gets hot, it doesn't burst into flames. Simple, really.

Why is a filament light bulb not filled with oxygen?
A filament light bulb is not filled with oxygen because oxygen can cause the filament to burn quickly. The bulb is usually filled with an inert gas like argon to prevent the filament from burning out too quickly and to protect it from oxidation.
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 would oxygen not be a suitable gas in a light bulb?
Oxygen is a reactive gas that can cause oxidation and combustion when exposed to high temperatures, which can be dangerous in a light bulb where the filament operates at high temperatures. Additionally, oxygen can accelerate the degradation of materials and reduce the lifespan of the filament, impacting the overall efficiency of the light bulb.
Why do bulb filament not burn?
The filament does not "burn", it just glows brightly. If some air were present in the bulb - as sometimes happens if a light bulb gets knocked and gets even a tiny crack in its glass bulb - then the oxygen present in ordinary air will quickly make the filament burn away.For more information see the answer to the Related question sghown below.
How it functions electric lamp?
An electric lamp, also known as a light bulb, functions by using electricity to heat a thin filament inside a glass bulb. As the filament heats up, it produces light. The bulb is filled with an inert gas to prevent the filament from oxidizing and burning out quickly. When the electricity flows through the filament, it causes the electrons to jump and emit photons, creating light.
Why is a filament light bulb not filled with oxygen?
A filament light bulb is not filled with oxygen because oxygen can cause the filament to burn quickly. The bulb is usually filled with an inert gas like argon to prevent the filament from burning out too quickly and to protect it from oxidation.
WHAT WILL HAPPEN IF THE ELECTRIC BULB S FILLED WITH OXYGEN GAS?
If an electric bulb is filled with oxygen gas, the filament inside the bulb would burn brighter and hotter than if it were filled with normal air. However, this can be dangerous as oxygen supports combustion and can increase the risk of a fire hazard if the filament overheats. It is not recommended to fill electric bulbs with pure oxygen gas.
What is the hot filament protected by?
The hot filament in an incandescent light bulb is protected by a glass bulb filled with an inert gas, such as argon or nitrogen. This gas prevents the filament from reacting with oxygen in the air, allowing it to glow and produce light.
Why the filament does not burn up when it gets hot?
As there is no oxygen in the surrounding. Usually bulb will be filled with inert gas or nitrogen. Oxidation is phenomenon of burning.
Why do you use Argon in a light bulb instead of oxygen?
The current flowing through the filament causes it to heat to a very high temperature - so high that is becomes incandescent (glows) and gives light. If the bulb was filled with oxygen then, at those high temperatures, the filament would oxidise - burn out - and the bulb would be "blown".
Why argon is filled in electric bulbs?
Argon is filled in electric bulbs to prevent the filament from burning out quickly. It helps to reduce the evaporation of the filament, prolonging the lifespan of the bulb. Argon also improves the efficiency of the bulb by creating a stable environment for the filament to glow.
Which gas in the air burn's out the filament?
Oxygen is the gas in the air that burns out the filament in an incandescent light bulb. When the filament reacts with oxygen at high temperatures, it oxidizes and eventually burns out.
Why are light bulbs filled with argon and not air?
Light bulbs are filled with argon instead of air because argon is an inert gas that helps prevent the filament from oxidizing and burning out quickly. Air contains oxygen, which can cause the filament to degrade faster due to oxidation. Argon creates a more stable environment inside the bulb, prolonging the life of the filament.
Why is there hardly any air in a glass bulb?
Hi! This is the question for this question! Because air was contained with oxygen and oxygen so oxygen with smallest heat it burns down the filament! This is also evacuated and filled with a gas which does not react with the red hot filament. So .... if air present the filament would quickly oxidise and fail to light up!
Why are electric bulbs filled with argon and nitrogen?
Electric bulbs are filled with argon and nitrogen because these gases can help prevent the filament inside the bulb from oxidizing and burning out quickly. The gases also reduce the rate of evaporation of the filament materials, which increases the lifespan of the bulb.
Why are only inert gases like Argon used in an electric light bulb?
If the lighter bulb had oxygen in it , the hot glowing filament would react with the oxygen, thereby destroying the filament. If the filament is destroyed, then there is no light. So an inert gas is used, because it will not react with the heated glowing filament. Hence the filament stays alight.
What stops the filament in a light bulb from Catching Fire?
The inert gas inside the light bulb prevents the filament from catching fire by creating an oxygen-free environment. This inhibits combustion reactions that would ordinarily allow the filament to ignite.
