Element Identification

The element with the electron configuration 4s23d5 is Manganese (Mn). Manganese is a transition metal located in the fourth period and the seventh group of the periodic table. Its atomic number is 25, and it is represented by the symbol Mn.

Physical Properties

Manganese is a hard, silvery-white metal with a melting point of approximately 1,244 degrees Celsius and a boiling point of about 2,025 degrees Celsius. It is relatively soft and can be cut with a knife. Manganese is paramagnetic, meaning it is attracted to a magnetic field. Its density is about 7.2 grams per cubic centimeter, and it has a face-centered cubic crystal structure.

Chemical Properties

Manganese is a highly reactive metal that readily forms oxides and other compounds. It has a variable oxidation state, typically +2 and +3, but can also exhibit +4 and +7 oxidation states. Manganese is known for its ability to form stable complexes with various ligands, which contributes to its diverse range of applications.

Occurrence and Isotopes

Manganese is the 25th most abundant element in the Earth’s crust, with an average concentration of about 0.1% by weight. It is found in various minerals, including pyrolusite, braunite, and psilomelane. Manganese has 25 isotopes, with the most stable being manganese-55, which has a half-life of about 2.6 million years.

Applications

Manganese has numerous applications in various industries. It is used in the production of steel, where it acts as a deoxidizing agent and improves the strength and toughness of the steel. Manganese is also used in batteries, fertilizers, and as a pigment in paints and inks. Additionally, it is employed in the production of special alloys, such as manganese bronze and manganese steel.

Health and Environmental Impact

Manganese is an essential trace element for humans and animals, playing a role in bone development, metabolism, and the formation of hemoglobin. However, excessive exposure to manganese can be harmful. High levels of manganese in the environment can lead to health issues, such as neurological disorders and kidney damage.

Conclusion

Manganese, with its electron configuration 4s23d5, is a fascinating element with a wide range of applications and properties.
