On Earth, you're mostly going to find it in the solid state.
If you meant "what US state" ... China is (by far) the world's leading producer of tungsten; as far as I'm aware, it's not mined in the US at all. Canada does produce some ... about 1% of what China does ... so it's possible there might be deposits in one or more of the states bordering Canada that simply aren't being exploited due to it not being economically feasible to do so at this point.
The oxidation state of tungsten in its most stable compound is 6.
Pens do not contain tungsten.
No but in tube lights it is there but that is not gaseous form of tungsten.
solid
They find the clue in Venice Italy. The swords they found were made of tungsten.
solid
Yes. You can find more details here: http://en.wikipedia.org/wiki/Tungsten#Isotopes
Tungsten begins to vaporize at 5828 K, 5555 °C, 10031 °F
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.
No. Because tungsten has a high boiling point of 5660 degrees Celsius before it can turn to its gaseous state. At normal room temperature,around 30 degrees Celsius, it is below its melting point of 3410 degrees Celsius, therefore it is more commonly seen as a solid
Tungsten metal doesn't have any charge. In its compounds, tungsten can have different oxidation states / charges. The most common formal oxidation state of tungsten is +6, but it exhibits all oxidation states from −2 to +6.
