Lets Tungstell A Story: Tyler Bond

Basic Information

  • Atomic Number: 74
  • Symbol: W
  • Atomic Weight: 183.84
  • Group: none
  • Period: 6
  • Color: Grayish White

Other Information

  • History:Discovered by Fausto and Juan Jose de Elhuyar in 1783 at Spain, from the Swedish words "Tung sten" meaning "heavy stone"
  • Uses:Tungsten is found in wolframite (iron-manganese tungstate, FeWO4/MnWO4) and scheelitez (calcium tungstate, CaWO4) ores. China produces 75% of the world's tungsten.
  • Description:Tungsten has the highest melting point and lowest vapor pressure of all metals
  • Biology (in humans):The metal oxidizes in air and must be protected at elevated temperatures
  • Geology ( in the universe):It has excellent corrosion resistance and is attacked only slightly by most mineral acids
  • Properties:Density of solid: 19250 kg m-3, Molar volume: |196| cm3, Thermal conductivity: |206| W m‑1 K‑1
  • Interesting Facts:The highest melting point and lowest vapor pressure of all metals, and at temperatures over 1650°C has the highest tensile strength.
