Symbol: MnAtomic Number: 25Atomic Weight: 54.938Classification: shift metalPhase at 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 obelisk of the regular table. The is classified as a transition metal. Manganese atoms have actually 25 electrons and also 25 protons v 30 neutrons in the many abundant isotope.Characteristics and PropertiesUnder standard conditions manganese is a solid metal with a silvery-gray color. In numerous ways manganese resembles iron, i m sorry is the facet next come it in the routine table. In its 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 when exposed to air. That will also slowly rust or decompose when coming into contact with water.Manganese is a relatively active element and can type a variety of oxidation states. The most stable is +2.Where is manganese discovered on Earth?Manganese is mostly discovered in the Earth"s crust where it is the twelfth many abundant element. The is discovered in a variety of minerals and also ores such together pyrolusite, bruanite, and also psilomelane. Trace quantities are discovered in ocean water and in the atmosphere.Most of the world"s manganese is uncovered in south Africa and also Australia. The most crucial ore the is mined is pyrolusite.A same amount the manganese is likewise expected to exist ~ above the ocean floor. However, it has actually been impractical and too expensive to harvest this manganese.

How is manganese used today?
The majority of manganese that is developed by market is for the manufacturing of steel alloys. It is provided widely in steel consisting of very solid steel and also in do stainless steel. The is likewise used in aluminum alloys, mainly in beverage cans wherein it increases the resistance against corrosion and also helps v the stiffness.Other applications encompass batteries, together an additive in gasoline, a colors in paint, and also as coloring in ceramics and glass.Manganese plays vital role in biological life. That is offered by a variety of enzymes. In the person body the is important for strong bones and liver and also kidney functioning. It is also important because that the process of photosynthesis in plants.How was it discovered?The first scientist to isolate the aspect manganese to be Swedish chemist Johan G. Gahn in 1774. Various other scientists had actually known the the existence of the aspect prior come this, however none had actually been able to isolate it.Where did manganese obtain its name?The name originates from the Latin native "magnes", which method magnet. It gets this name due to the fact that its link are provided in making glass. Don"t get perplexed though, in spite of its name, manganese is no magnetic.IsotopesManganese has actually one stable isotope in nature, manganese-55.Interesting Facts around ManganeseIt was once considered part of the "iron group" of elements as it was on the heat of transition metals v iron and had similar characteristics come iron.It is thought that overexposure come manganese can cause some neurological (brain) disorders.Although we require it to survive, our body cannot store manganese.Manganese dioxide was offered as paint plenty of thousands of years ago.An adult human will have a full of roughly 12 mg of manganese in your body.
