Top 10 interesting facts about Manganese

  • Manganese was discovered in 1774 by Johann Gahn. Manganese's name derives from the Latin word "mangnes" which means "magnet".
  • Manganese's boiling point is at 1962.0 C (2235.15 K, 3563.6 F) and melting point at 1245.0 C (1518.15 K, 2273.0 F).
  • Manganese is found in nature as a free element and also in chemical compound with iron.
  • Manganese is a grey/silver metal and it oxidizes very easily.
  • Manganese has one stable isotope 55-Mn and six other isotopes with half-life from 1.45 minutes 57-Mn to 3.7 million years 53-Mn (other 12 isotopes are known with very short half-life; less than a minute).
  • Manganese is the 12th most abundant element in Earth's crust (0.1%).
  • South Africa has the largest resources of manganese in the world.
  • Manganese is used in metallurgy in iron and steel production but its most important application is in alloy production.
  • Manganese is an essential element in all forms of life.
  • In human body, most of the manganese is stored in bones, kidneys, tissue, and liver.
