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.

The metal will melt if you do that.
If they were not evacuated of all outside air, the filament will burn up in seconds because the air Will cause Resistance, thus the filament will burn brighter and brigther tyring to burn off the air until it opens. (blown bulb)...
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.
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.
No, the bulb will not light if the filament is broken because the filament is the part of the bulb that creates light when electricity passes through it. Without a functioning filament, there is no source of light in the bulb.

ts filament will not burn
The 'Filament' of a lightbulb is a peice of metal with an unusually high melting
Because the filament will burn, and the filament is the part that produces the light.
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.
A light bulb is sealed to prevent air from entering the bulb, which can cause the filament to burn out quickly. The vacuum or inert gas inside the bulb helps to preserve the longevity of the filament and ensures consistent lighting performance.
Argon is used in light bulbs because it is an inert gas, which means it does not react with the filament or the glass envelope of the bulb. This helps to extend the life of the bulb by preventing the filament from degrading. Additionally, argon helps to reduce the rate of evaporation of the filament, leading to a longer-lasting bulb.
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.
The filament of a light bulb does not burn because it is made of a material, typically tungsten, that has a high melting point and is able to withstand the high temperatures generated by the electric current passing through it. Additionally, the filament is enclosed in a vacuum or inert gas to prevent it from reacting with oxygen and burning up.
filament of bulb
An electrical current is passed through the high resistance filament in the bulb, causing it to become white hot and so give off light. The inside of the bulb is filled with an inert gas, such as nitrogen, so the filament does not burn up .
