 Post subject: Tungsten . . . in Technicolor!
PostPosted: Wed Feb 18, 2009 12:09 am 
1. Tungsten ranges in color from steel gray to white.

2. Tungsten has the highest melting point of all metals.

3. Tungsten is the strongest of all metals.

4. While it is resistant to corrosion, Tungsten can oxidize, and occasionally needs protection, particularly in higher elevations like Utah.

5. The atomic symbol for Tungsten is W.

6. The atomic number of Tungsten is 74.

7. The atomic weight of Tungsten is 183.84.

8. About 75% of the world's Tungsten supply is found in China.

9. Pure Tungsten does not occur naturally, but is found in compounds. While pure Tungsten is extremely strong, natural compounds containing Tungsten are actually quite brittle.

10. Because Tungsten is so strong, it has MANY applications. Some include jewelry, wire for electronics, high-end tools, NASA space equipment (it can withstand very high temperatures during takeoff), and lighting filiments.

11. The electron configuration of Tungsten is 1s2 2s2p6 3s2p6d10 4s2p6d10f14 5s2p6d4 6s2. (Translate THAT if you can!)

12. The most stable form of Tungsten contains 110 neutrons per molecule.

13. The boiling point of Tungsten is 5655 degrees Celcius.

14. The melting point of Tungsten is 3407 degrees Celcius.

15. At room temperature, Tungsten is solid.

16. Tungsten was discovered by Fausto and Juan José de Elhuijar of Spain in 1783.

17. The word Tungsten is derived from the Swedish words "tung sten", which translate to heavy Stone.

18. The W symbol which represents Tungsten comes from the word wolframite, a compound discovered by Peter Woulfe in 1779. Wolframite was later found to contain the element.

19. The world produces approximately 45,100 tons of Tungsten annually for commercial use.

20. The two naturally occurring compounds which contain Tungsten are Wolframite and Scheelite.

21. When tungsten crystallizes, it forms a cubic structure. (I'd imagine that this makes Tungsten rings a bit difficult to form, but I don't know how the jewelry industry works. Anybody know the answer to this one?)

22. The most common use for Tungsten in the United States is to make wear resistant tools.

23. The density of Tungsten is 19.3 grams per cubic centimeter.

24. The correct pronunciation of this element is TUNG-sten.

25. Tungsten can be very toxic if handled improperly. In liquid, steam, or powder form, it is irritating to the skin, eyes, and lungs. No issues have been found with the longterm, safe handling of Tungsten.

All knowledge is power. Read enough factoids and you will be as strong as Tungsten.
