Top 12 interesting facts about Zinc

  • Zinc was discovered by Andreas Marggraf in 1746. Its name derives from the German word "zin" which means "tin".
  • Zinc's melting point is at 419.58 C (692.73 K, 787.24396 F) and its boiling point is at 907.0 C (1180.15 K, 1664.6 F).
  • Zinc is a bluish-white hard metal, less dense than iron.
  • Zinc is the 24th most abundant element in the Earth's crust.
  • The most common zinc ore is called sphalerite.
  • The major zinc's application is plating of iron due to its resistance to corrosion. Other important applications are in batteries and different alloys.
  • The largest deposits of zinc are in Iran, Australia, the USA, and Canada.
  • Zinc has five naturally occurring isotopes: 64-Zn, 66-Zn, 67-Zn, 68-Zn, and 70-Zn. 64-Zn is the most abundant, more than 48% occurrence.
  • Zinc is a moderately reactive metal and strong reducing agent.
  • Zinc reacts with the carbon dioxide from the atmosphere forming a protective layer which prevents it from further reaction with air and water.
  • Zinc is the 4th most common used metal, after iron, aluminum, and cooper.
  • Zinc is included in all daily vitamins and mineral supplements.
