Symbol: MnAtomic Number: 25Atomic Weight: 54.938Classification: shift 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 very first element in the seventh pillar of the regular table. It is classified as a shift metal. Manganese atoms have actually 25 electrons and 25 protons v 30 neutron in the many abundant isotope.Characteristics and PropertiesUnder standard problems manganese is a solid metal with a silvery-gray color. In many ways manganese resembles iron, i m sorry is the element next to it in the routine table. In that pure form, it is for this reason brittle that it can"t be machined without breaking.Pure manganese have the right to have a shining surface, but tarnishes once exposed come air. The will additionally slowly rust or decompose when coming into contact with water.Manganese is a fairly active element and also can kind 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 wherein it is the twelfth many abundant element. It is discovered in a number of minerals and also ores such together pyrolusite, bruanite, and also psilomelane. Trace amounts are discovered in s water as well as in the atmosphere.Most that the world"s manganese is discovered in southern Africa and Australia. The most necessary ore the is mined is pyrolusite.A fair amount that manganese is also expected to exist top top the ocean floor. However, it has been impractical and too expensive to harvest this manganese.

How is manganese provided today?The bulk of manganese that is developed by industry is for the manufacturing of steel alloys. It is used widely in steel including very solid steel and also in make stainless steel. It is likewise used in aluminum alloys, primarily in beverage cans where it boosts the resistance versus corrosion and helps through the stiffness.Other applications incorporate batteries, together an additive in gasoline, a colours in paint, and as color in ceramics and glass.Manganese plays crucial role in biological life. The is used by a variety of enzymes. In the person body it is crucial for solid bones and liver and also kidney functioning. That is likewise important because that the process of photosynthesis in plants.How was it discovered?The very first scientist to isolation the aspect manganese was Swedish chemist Johan G. Gahn in 1774. Other scientists had known the the visibility of the facet prior come this, however none had been able to isolation 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 compound are offered in making glass. Don"t get confused though, despite its name, manganese is no magnetic.IsotopesManganese has actually one secure isotope in nature, manganese-55.Interesting Facts around ManganeseIt was when considered component of the "iron group" of elements as it to be on the heat of transition metals with iron and had similar characteristics come iron.It is assumed that overexposure to manganese can reason some neurological (brain) disorders.Although we require it come survive, our bodies cannot save manganese.Manganese dioxide was offered as paint plenty of thousands of years ago.An adult human will have a total of around 12 mg of manganese in your body.
