Tungsten (pronounced /tʌŋstən/), also known as wolfram (/wlfrəm/), is a chemical element with the chemical symbol W and atomic number 74. Tungsten is one of the heaviest materials after gold, for the density of tungsten is 19.25 g•cm3(near r.t.).
Tungsten is one of the Nonferrous Metals, and also it is as molybdenum and rare earths which are Refractory Metals.
It is also used in eletrical bulbs as filament.
What else can I help you with?
Is tungstan a metal?
No, but tungsten is. In most other countries it is called wolfram.
Why tungstan light bulb generates so much heat?
The heating of the wire causes light to be emitted.
What is filament of light bulb made of?
Filament of bulb is made up of Tungsten.perfect answer:filament of bulb made of tungsten because of its melting point tungsten s m.p. is 3422 c and it produces through a method called extrusion process and due to its high melting point it do not melt due to heat. thnx if any1 have some general knowledge plz send me at wanted_rk2000@yahoo.comTungsten.
How can flame testing be improved?
Depending on the metal or metal salt you are flame testing a different colour will often result. The different colours are due to the separation of the electron orbitals. In the excited stated the electrons have taken energy from the flame. When they relax they give off radiation, most commonly in the form of visible light. Copper for example is blue/green and strontium is pink/red and magnesium is white. Other metals such as tungstan give off radiation in the x-ray range. Neon can be made to give off many different colours depending on its pressure.
