Manganese element in Periodic table

The Manganese element (Mn) has the atomic number 25 and is located in group 7 and period 4. Manganese is a metal and it is classified as a transition element.

Facts about manganese

Here are a few interesting facts about manganese element.

1. Manganese is the 12^th most abundant element found from the earth’s crust.
2. Around 75% of the total manganese resources comes from South Africa, which makes it a leading producer of manganese in the entire world.
3. Most of the manganese (around 85% to 90%) is used in manufacturing of steels.
4. Manganese is brittle than iron, but it has more hardness than iron.
5. The manganese occupies around 0.1% (by weight) of the earth’s crust.
6. Manganese is also required by the human body to perform metabolic activities.

Properties of manganese

Here is a list of some physical properties and chemical properties of manganese.

Physical properties of manganese

• Manganese has a solid metal having a silvery white appearance.
• Manganese has a shiny surface when it is polished, but it gets tarnished easily when it is exposed to air.
• Manganese has a density of 7.47 g/cm³ and its atomic mass is 54.938 u.
• Manganese is not malleable because it is strong but brittle in nature.
• The melting point and boiling point of manganese is 1519 K and 2334 K respectively.

Chemical properties of manganese

• Manganese is a reactive metal and because of this reason it is not found in free state from the earth’s crust. It is always found as a compound with other elements.
• There are many isotopes of manganese. Out of these isotopes, the most abundant isotope is ⁵⁵Mn.
• When pure manganese comes in contact with water, it easily gets corroded.
• The electronic configuration of manganese is [Ar] 3d⁵ 4s² which has incomplete d-orbitals.

Uses of manganese

Here are some uses of the manganese element.

• Manganese is widely used in steel manufacturing industries as well as it is also used in making glass and other materials.
• Manganese is used in aluminum alloys for manufacturing the cans for storage of beverages.
• Manganese is also present in the human body and our body requires manganese for proper metabolic activities. The human body gets the manganese from foods like eggs, spinach, rice, nuts, etc.
