Tungsten is not a rock. It is an element. Its atomic number is 74 and abbreviation is W (which stands for Wolfram, its other name)
tungsten carbide
Mining
Halogen gas is in a Tungsten-Halogen Light Bulb.
Tungsten Carbide is made from compounds of Tungsten and Carbon. At the base level, Tungsten Carbide resembles a type of fine dark powder. This powder then made into shapes by being pressed.
It's man made. You can't find tungsten metal in the earth the way you can find gold. What occurs is a rock containing a metal compound, for instance the ore scheelite which contains calcium tungstate. Tungsten is extracted from it by first converting it to tungsten oxide and then reducing this with hydrogen.

Tungsten is represented by the symbol W which came from its earlier name of Wolfram. Tungsten comes from Tung Sten, the Swedish words meaning heavy stone.
The name for tungsten originates from the Swedish words "Tung" and "sten." This two words have the literal meaning of "heavy stone.' Discovered in 1783 in a mineral called wolframite, tungsten is classified as a metal.
If it is necessary is possible. This depends on the type of compound.
No. Tungsten is an element, where as tungsten carbide is an alloy, or a mixture of elements (tungsten, nickel, tantalum, niobium, titanium, and chromium). Tungsten carbide is much easier to work into styles and designs, but does not change the hardness of the metal.
