Who Discovered Manganese?
Posted In: Chemical Elements.
The Manganese should not be mistaken for the metal magnesium. They are two, completely different elements. Below are a few interesting facts about the man who discovered this element and about the material itself.
Carl Scheele and Johan Gahn
The year of 1774, Mr. Carl Scheele offered a proposal about the existence of this unknown element. Although he gets a portion of the recognition, the real discoverer was a chemist by the name of Johan Gottlieb Gahn. He successfully isolated the element by mixing manganese dioxide with carbon.
Manganese appears as a solid grey metal at a normal, room temperature setting. This is the twelfth most accessible element that is found in the crust of our Earth. This is an essential element for every life form. In all humans, this element is kept in the liver and in the kidneys, Even before humans knew that our bodies needed this, it was there.
Just a single, stable isotope exist
Many countries still currently farm Manganese. A few of those are South Africa, Gabon and Kazakhstan. There is just one lone, stable isotope in this element. Manganese elements were used well before they were discovered in the year of 1174, by the Greeks and the Romans. Other countries use many workers even today to mine out the elements of Manganese. There are close to 10 other countries that continue mining this abundant element.
Properties of manganese
This chemical has the sign of MN. Its atomic rating is 25. It can be typically sought out because it is an element that is considered free, or it can be infused with iron as well. Manganese is vital to such things as stainless steel. It has metal alloy that is critical to industrial metal. In the past, manganese has been found primarily in dark minerals such as pyrolusite. In Greece, they were able to discover other forms of this mineral. Magnetite was one of their discoveries. This opened up other options for scientists all around the world.
The mineral pyrolusite
Chlorine was actually derived from the pyrolusite. Chemist, Carl Scheele was the person responsible for this discovery. Following that discovery, Johan Gahn was successful in isolating and creating a pure manganese. He was able to do this by removing the dioxide. This can be used for the prevention of decomposing and rusting on metals. The discovery made other industries take another look at how to manufacture and use steel products.
Manganese can be poisonous
Depending upon the variations, it may be used to provide pigment in the industrial field. If you look into Biology, you will find that alkaline metals are strong elements that oxidize metals naturally. This element can also react with oxygen in photosynthetic plants. It is also a required mineral for every living organism. Just as with any other element, if mammals are exposed in large quantities to manganese, it can act as a poison and can even cause death. If you were to place manganese and iron together on a table, you would notice how similar both elements is to the other.
Been in use since the Stone Age
It is reported that these minerals have been in use since the Stone Age. It is not a magnetic element and was utilized to help to add color to glass and other handmade products.
