Fluorescent tubes create ultraviolet light when electricity is passed through Mercury vapor. The UV light causes the phosphors, dusted over the inside of the tube, to fluoresce--or give off visible light. Three of the elements found in the tube would be: Phosphorous, mercury, and tungsten.
A halogen bulb is an incandecent bulb with a filament made from tungsten which is contained within an inert gas and a small amount of a halogen such as bromine or more comonly iodine. The halogen gas combined with the tungsten filament produces a chemical reaction known as a halogen cycle which increases the lifetime of the filament and prevents blackening of the inside of the bulb by redepositing tungsten from the inside of the bulb back onto the filament. This means it is more effciant.
Tungsten is an element often found in cheaper light bulbs.
In any fluorescent tubes that are minute amounts of the element mercury.
tungsten <<>> Also along with the above, aluminium for the shell, steel for the filament holders, and in past years brass was used for the shell until manufactures found out it was cheaper to use aluminium for the job.
neon
argon
Generally, tungsten.
sodium is used in street lights,thats why they have a yellowish/orange colour Answer: Neon & Argon are used in light bulbs.
Tungsten is an element often found in cheaper light bulbs.
Mercury Vapor
Tungsten, as it burns long and brightly.
Argon(or nitrogen) and tungsten are used in incandescent light bulbs.
