Symbol: MnAtomic Number: 25Atomic Weight: 54.938Classification: change metalPhase in ~ Room Temperature: SolidDensity: 7.21 grams per centimeter cubedMelting Point: 1246°C, 2275°FBoiling Point: 2061°C, 3742°FDiscovered by: Johan G. Gahn in 1774Manganese is the first element in the seventh column of the periodic table. That is classified together a shift metal. Manganese atoms have 25 electrons and also 25 protons v 30 neutrons in the most abundant isotope.Characteristics and PropertiesUnder standard problems manganese is a solid steel with a silvery-gray color. In many ways manganese resembles iron, which is the facet next come it in the routine table. In its pure form, it is for this reason brittle the it can"t it is in machined without breaking.Pure manganese can have a shiny surface, yet tarnishes when exposed come air. It will likewise slowly rust or decompose once coming into contact with water.Manganese is a reasonably active element and also can form a number of oxidation states. The most stable is +2.Where is manganese discovered on Earth?Manganese is mostly found in the Earth"s crust where it is the twelfth most abundant element. The is found in a number of minerals and also ores such together pyrolusite, bruanite, and also psilomelane. Trace amounts are uncovered in ocean water as well as in the atmosphere.Most that the world"s manganese is discovered in southern Africa and Australia. The most vital ore that is mined is pyrolusite.A same amount of manganese is likewise expected come exist ~ above the s floor. However, it has been impractical and also too expensive to harvest this manganese.

How is manganese supplied today?
The bulk of manganese the is developed by sector is for the production of metal alloys. It is used widely in steel consisting of very strong steel and in make stainless steel. That is additionally used in aluminum alloys, primarily in beverage cans where it rises the resistance against corrosion and helps through the stiffness.Other applications encompass batteries, as an additive in gasoline, a colors in paint, and as coloring in ceramics and also glass.Manganese plays critical role in organic life. The is used by a variety of enzymes. In the person body it is important for solid bones as well as liver and also kidney functioning. The is also important for the process of photosynthesis in plants.How to be it discovered?The very first scientist to isolation the aspect manganese to be Swedish chemist Johan G. Gahn in 1774. Other scientists had known the the presence of the aspect prior come this, however none had actually been maybe to isolate it.Where go manganese acquire its name?The name originates from the Latin indigenous "magnes", which method magnet. It it s okay this name since its compounds are offered in do glass. Don"t get puzzled though, despite its name, manganese is not magnetic.IsotopesManganese has actually one steady isotope in nature, manganese-55.Interesting Facts about ManganeseIt was when considered part of the "iron group" of facets as it to be on the row of shift metals with iron and also had comparable characteristics to iron.It is assumed that overexposure to manganese can cause some neurological (brain) disorders.Although we need it come survive, our body cannot keep manganese.Manganese dioxide was offered as paint plenty of thousands of year ago.An adult human will have a complete of around 12 mg of manganese in their body.
