Tungsten occurs naturally on Earth. It is expected to have been produced by the same supernovae that produced our other heavy elements. It was first identified by Johan Gottschalk Wallerius in 1747. There are mines in Europe and China that produce most of it. A few mines in North and South America. I hope I guessed which "origin" you intended...
What is more efficient a tungsten light or an incandescent light?
yes
Technically no, since an element defines that it is a single atom. Tungsten Carbide is a chemical compound consisting of Tungsten and Carbon (W2C) and Graphite is a form of pure carbon
The melting point of Tungsten is 3,422°C (degrees celsius,) or 3695K (Kelvin.)The melting point of tungsten is3695 K (Kelvin)3422 °C (Celsius)6192 °F (Fahrenheit)
Wolfram is what tungsten used to be called, which is why W is its chemical symbol.
The symbol for tungsten is W and it comes from wolfram which is another name for tungsten.Also the ore of tungsten is wolframite with could be the origin of the chemical symbol.
The name Tungsten is Swedish in origin meaning "scheelite".
Tungsten's original name is Wolfram that is why the symbol for Tungsten is a W
Tungsten is not Magnetic :(
can you dissolve tungsten
That's tungsten. Wikipedia has more in their post on this amazing metal. A link to it is below.
Tungsten's original name is Wolfram that is why the symbol for Tungsten is a W
There are none, tungsten is a pure element so it is made of only tungsten.
Tungsten is found in wolframite (hence why the Germans called tungsten wolfram).
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.
We should be strong as tungsten heavy alloy,tough as tungsten carbide.This is the motto of China Tungsten Online
Tungsten is really a semiconductor.
