About Manganese

Manganese is a chemical element with the symbol Mn and atomic number 25, meaning every atom has 25 protons in its nucleus. It is classed as Transition metal and is a solid at room temperature. Its atomic mass is about 54.938 atomic mass units (u).

On the periodic table, Manganese sits in group 7, period 4, which determines how many electron shells it has and how it tends to react with other elements.

Uses of Manganese

In daily life and industry, Manganese is used for Steel, batteries. These uses are closely tied to the typical properties of elements in the Transition metal category.

Electron Structure of Manganese

Using a simplified electron shell model (at most 2 electrons in the first shell, 8 in the second, 18 in the third, and so on), Manganese has 3 electron shells, with an approximate arrangement of 2, 8, 15 electrons from the innermost shell to the outermost. This is a simplified learning model, not the full electron configuration that accounts for the s, p, d and f subshells.
