    What is Manganese

    Manganese metal is classified as a transition metal, and chemically manganese is an element. The density of manganese is 7.43 grams per cubic centimeter. Manganese is found in the solid state at room temperature, with a melting point of 1246 °C (2275 °F) and a boiling point of 2061 °C (3742 °F). Manganese has an atomic mass of 54.938 AMU, atomic number 25, and symbol (Mn). In the Periodic Table, Manganese is located in Group 7, Period 4 and Block (D). Its atom has 25 electrons, 25 protons, 30 neutrons and 4 energy levels.

    Manganese was discovered by the Swedish chemist Johan Gottlieb Gahn in 1774.

    Properties of Manganese

    • Manganese is a lustrous metal of silver-grey colour. In which there is a glimpse of light pink color.
    • Manganese is a hard and brittle metal. Manganese in its pure state is too brittle to be machined.
    • Manganese is a chemically active element, so it is not found in pure state in nature.
    • Manganese reacts with oxygen present in the air to form manganese dioxide, this reaction is very rapid at high temperature.
    • When exposed to water, manganese rusts like iron, in cold water this reaction is slow, while in hot water and steam this reaction is very rapid.
    • Manganese dissolves in most acids and produces hydrogen gas.
    • Manganese powder is highly flammable, and it burns with a bright white light when ignited.

    Uses of Manganese Metal

    • Mostly manganese is used to make alloys.
    • About 1% manganese is added to steel, this increases the strength of the steel.
    • Manganese-steel contains about 13% manganese, it is a very strong steel. This steel is used for rifle barrels, railway tracks, safes and prison bars.
    • Drink cans are made from this alloy by adding 1.5% manganese to aluminium.
    • Manganese oxide is used as a catalyst.
    • Manganese is essential for all living beings, and it is an essential nutrient for our body. We need about 2 - 4 mg of manganese per day, it is necessary for our body's use of vitamin B1, and it is a key component of many enzymes our body makes. Apart from this, it is also necessary for the functioning of kidney and liver in our body.
    • Manganese is used in fertilizers.
    • Manganese is used in dry cell batteries to prevent hydrogen build-up.
    • Manganese is used to remove the green color in glass.
    • Manganese is used as a drying agent in black paint.
    • Manganese is used to make violet colored glass.
    • Manganese is essential for photosynthesis in plants.

    Interesting Facts about Manganese

    • Manganese is the 12th most abundant element in the earth's crust.
    • Manganese nodules are found at the bottom of the sea, these nodules contain about 24% manganese. According to scientists, reserves of 1.5 Trillion Tons of manganese nodules can be present on the ocean floor.
    • More than 90% of the total manganese produced each year is used in steel production.
    • About 12 milligrams of manganese is present in the body of an adult.
    • Manganese in excess is toxic to health. Excessive exposure to manganese can cause serious diseases related to the nervous system and brain.
    • Manganese dioxide has been used as a paint for thousands of years.
