Symbol: MnAtomic Number: 25Atomic Weight: 54.938Classification: change metalPhase at Room Temperature: SolidDensity: 7.21 grams per cm cubedMelting Point: 1246°C, 2275°FBoiling Point: 2061°C, 3742°FDiscovered by: Johan G. Gahn in 1774Manganese is the an initial element in the seventh obelisk of the routine table. It is classified as a shift metal. Manganese atoms have 25 electrons and also 25 protons v 30 neutron in the many abundant isotope.Characteristics and also PropertiesUnder standard problems manganese is a solid metal with a silvery-gray color. In countless ways manganese resembles iron, which is the element next to it in the regular table. In that is pure form, the is for this reason brittle that it can"t it is in machined there is no breaking.Pure manganese have the right to have a shining surface, but tarnishes once exposed to air. The will additionally slowly rust or decompose as soon as coming into call with water.Manganese is a reasonably active element and also can type a variety of oxidation states. The most stable is +2.Where is manganese found on Earth?Manganese is mostly found in the Earth"s crust whereby it is the twelfth most abundant element. The is found in a number of minerals and ores such together pyrolusite, bruanite, and psilomelane. Trace amounts are uncovered in ocean water and also in the atmosphere.Most the the world"s manganese is found in southern Africa and also Australia. The most essential ore the is mined is pyrolusite.A fair amount of manganese is likewise expected come exist ~ above the s floor. However, it has been impractical and too expensive come harvest this manganese.

How is manganese used today?
The bulk of manganese the is created by market is because that the manufacturing of metal alloys. That is offered widely in steel including very solid steel and in make stainless steel. That is also used in aluminum alloys, generally in beverage cans where it rises the resistance against corrosion and also helps v the stiffness.Other applications incorporate batteries, as an additive in gasoline, a pigment in paint, and also as color in ceramics and also glass.Manganese plays critical role in biological life. That is supplied by a variety of enzymes. In the human being body that is important for solid bones and liver and also kidney functioning. The is additionally important for the procedure of photosynthesis in plants.How to be it discovered?The an initial scientist to isolate the element manganese to be Swedish chemist Johan G. Gahn in 1774. Other scientists had known the the visibility of the element prior to this, but none had been may be to isolate it.Where go manganese get its name?The name originates from the Latin native "magnes", which way magnet. It gets this name since its link are offered in making glass. Don"t get puzzled though, regardless of its name, manganese is not magnetic.IsotopesManganese has actually one secure isotope in nature, manganese-55.Interesting Facts around ManganeseIt was when considered component of the "iron group" of facets as it to be on the row of change metals with iron and had comparable characteristics come iron.It is believed that overexposure come manganese can cause some neurological (brain) disorders.Although we need it to survive, our bodies cannot save manganese.Manganese dioxide was used as paint plenty of thousands of year ago.An adult human being will have actually a full of about 12 mg the manganese in your body.
