Step 1 : Introduction to the question "7. Tungsten has the symbol 'W', but what does the letter 'W' stand for?"
...1. Wyoming 2. Waring 3. Warsaw 4. Wolfram The 'W' is from the German word 'Wolfram', which is derived from the name of one of tungsten's ores, Wolframite. Wolframite has the delightfully cute meaning of "the devourer of tin". Wolframite was given this name as it can hinder the process of tin smelting. Wyoming is, of course, a state in the U.S.A, Warsaw is the capital city of Poland and Edward Waring was an eighteenth century mathematician who conducted a great deal of work relating to disintegrating numbers and calculating how these numbers were composed of the sum of prime numbers or their powers. Unfortunately, these are incorrect.
