Zinc | Chemical elements

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).

Top 10 interesting facts and information about zinc

  1. Zinc is a bluish-white hard metal, less dense than iron.
  2. Zinc is the 24th most abundant element in the Earth’s crust.
  3. The most common zinc ore is called sphalerite.
  4. The major zinc’s application is plating of iron due to its resistance to corrosion. Other important applications are in batteries and different alloys.
  5. The largest deposits of zinc are in Iran, Australia, the USA, and Canada.
  6. 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.
  7. Zinc is a moderately reactive metal and strong reducing agent.
  8. Zinc reacts with the carbon dioxide from the atmosphere forming a protective layer which prevents it from further reaction with air and water.
  9. Zinc is the 4th most common used metal, after iron, aluminum, and cooper.
  10. Zinc is included in all daily vitamins and mineral supplements.
