Element of the day
  • 76 – Osmium – Os
  • Osmium is the hardest metal element, and is at least as expensive as rhenium.
  • Osmium and iridium are alloyed in an incredibly hard and wear resistant material that was used in fountain pens and phonograph needles.
  • Osmium powder reacts with the air to produce a vapor called osmium tetroxide which is deadly.
  • Osmium is the densest element.
