tungsten
Tungsten ( chemical name Wolfram ) is used for the filament of an incandescent lamp. This is due to ability for making fine guage Tungsten wires , mechanical strength of such wires and the High melting point , which is considerably more than the normal operating temperature of the filament.
go to the link below and it will tell you all the chemical properties of tungsten:
Generally, tungsten.
Tungsten is a chemical element. The symbol for Tungsten is W.
Tungsten (wolfram, W) ia chemical element, not a property.
The physical property that can render tungsten suitable for making filament of tungsten light bulbs is incandescence.
Tungsten, W, with the highest melting point of all elements: 3680 K
It is a physical change. When you supply electricity, the electrons jump to higher energy state. When they come back to their level, it emits energy which falls in the visible region of light. The atoms of the filament (Tungsten) are not going through any change, that changes their chemical properties. Tungsten, still remains tungsten!
Any noble gas except helium, or beryllium used in WWII is now dangerous or tungsten, copper, zinc, nickel, fluorine, mercury, titanium, and carbon Tungsten Filament is used in Incandescent Lamps and Fluorescent Lamps Tungsten and Argon are used in incandescent light bulbs. Tungsten (chemical symbol 'W', 74)
Tungsten.
There are two types of lamps the tungsten halogen lamps and incandescent lamps. Tungsten Halogen Lamps are similar to incandescent lamps and produce light in the same manner from a tungsten filament; however the bulb contains a halogen gas (bromine or iodine) which is active in controlling tungsten evaporation, whereas the incandescent lamp suppresses tungsten evaporation.
What is more efficient a tungsten light or an incandescent light?
Physical change. You aren't changing the substance.
