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.

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.
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 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.
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
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.
Which gas used in light bulb?
The gas in a light bulb is Argon
What gas is inside a light bulb?
The kind of gas that is in a light bulb is called Argon.
What the name of the gas is in a light bulb?
argon - inert gas
What gas stops a light bulb burning?
ARGON
What are the materials of a light bulb?
glass and argon gas .
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.
What kind of gas goes in an incandescent light bulb?
An inert gas such as argon.
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.
Which gas is used in light bulb?
regular light bulbs have argon and/or nitrogen
What gas is in light bulbs?
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.
Which gas is filled in light bulb?
Light bulbs are filled up by Neon or Argon gases, because they are inert.
What element fills lightbulbs?
Tungsten <<>> An inert gas fills the light bulb. The gas is usually argon
