Fluorescent light tubes contain a small amount of noble gas, typically argon or neon, which helps to initiate the lighting process. When electricity passes through the gas, it produces ultraviolet light that excites the phosphor coating inside the tube, resulting in visible light. However, the fluorescent light tube itself is not a noble gas; it is a sealed glass tube filled with gas and phosphor materials.
What else can I help you with?
What inert gas gives its name to fluorescent lights?
Inert gases are noble gases. I assume that you have heard of Neon Lights? Ne (neon) is a noble gas. When energy (heat) is added to the element then the valance electrons move up to the excited state, or a higher principal energy level. It emits red light when the electrons return to the ground state.
What noble gas is in period 4?
Krypton is the noble gas found in period 4 of the periodic table. It has the atomic number 36 and is known for its fluorescent light applications.
How does 4 tube fluorescent work?
A 4-tube fluorescent light contains four fluorescent tubes connected to a ballast that regulates the electrical current flowing through the tubes. When the light switch is turned on, the ballast sends high voltage to the tubes to ionize the gas inside. This ionization process produces ultraviolet light, which then interacts with the phosphor coating inside each tube to produce visible light.
What does fluorescent strips mean?
Fluorescent strips typically refer to long, narrow tubes filled with fluorescent gas that produce light when an electrical current passes through them. These strips are commonly used in overhead lighting fixtures in commercial and industrial settings.
Quicksilver used in fluorescent light tubes?
"Quicksilver" is an older name for the element mercury, which is used in fluorescent tubes. The average Compact Fluorescent Tube (CFT) contains 4 mg Hg. By comparison the old 48" tube contains 10-25 mg Hg in vapour and liquid form.
Inert gas use to make bright city light?
Fluorescent tubes contain argon.
What material lines the tubes of fluorescent lights and glows to UV Light?
Phosphor coating lines the inside of fluorescent light tubes. When the gas inside the tube is excited by electrical current, it emits ultraviolet (UV) light. The phosphor coating then absorbs the UV light and re-emits it as visible light, creating the glow from the fluorescent light.
What inert gas gives its name to fluorescent lights?
Inert gases are noble gases. I assume that you have heard of Neon Lights? Ne (neon) is a noble gas. When energy (heat) is added to the element then the valance electrons move up to the excited state, or a higher principal energy level. It emits red light when the electrons return to the ground state.
What gases are in cold cathode fluorescent tubes?
It can be any noble gas (though it's never helium). Normally Neon but occasionally argon, krypton and xenon.
What noble gas is in period 4?
Krypton is the noble gas found in period 4 of the periodic table. It has the atomic number 36 and is known for its fluorescent light applications.

What was argon used for?
Argon is used in various applications including welding, lighting, and electronics. It is commonly used as a shielding gas in welding to prevent oxidation of the metal being welded. In lighting, argon is used in fluorescent tubes to help create the initial glow of the light.
What element is in fluorescent light tubes?
Fluorescent light tubes contain mercury vapor as well as an inert gas, such as argon or krypton. When an electric current passes through the tube, it excites the mercury vapor, causing it to emit ultraviolet light that is then converted into visible light when it interacts with the phosphor coating inside the tube.
What gas is in fluorescent tube?
The gas in a fluorescent light bulb tube is composed of mercury, along with argon, xenon, krypton or neon. It is important to dispose of the tubes properly after they are used, since mercury can be toxic to people and animals if it is released into the environment.
What does fluorescent strips mean?
Fluorescent strips typically refer to long, narrow tubes filled with fluorescent gas that produce light when an electrical current passes through them. These strips are commonly used in overhead lighting fixtures in commercial and industrial settings.
What gases are used in fluorescent light bulbs?
Fluorescent lamps (both the "compact" variety and the long tubes) are filled with inert gas (argon, xenon, neon or krypton) and mercury vapor, under low pressure (less than 1% of atmospheric pressure)Neon. and lead
What is the difference between the normal light globe and a fluorescent tube?
"Normal" light globes use a glowing filament, heated by the current. Flourescent tubes ignite a gas within a tube, using an arc.
