**Understanding the Electron Configuration of Manganese**

Manganese is a chemical element with the atomic number 25, which means it has 25 electrons. The electron configuration of an atom is a way to describe how the electrons are arranged in the various energy levels or shells around the nucleus. In this article, we will explore the subshells that hold the 25 electrons in a manganese atom in order of increasing energy.

The Electron Configuration of Manganese

The electron configuration of manganese can be written as 1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁵ 4s². This configuration tells us that the first two electrons are in the 1s subshell, the next four electrons are in the 2s and 2p subshells, the next six electrons are in the 3s and 3p subshells, the next five electrons are in the 3d subshell, and the last two electrons are in the 4s subshell.

Subshells and Their Energy Levels

To understand the electron configuration of manganese, we need to know about the subshells and their energy levels. The subshells are the regions around the nucleus where the electrons are located. The energy levels of the subshells are determined by the principal quantum number (n), the azimuthal quantum number (l), and the magnetic quantum number (m).

1s subshell: The 1s subshell is the innermost subshell and has the lowest energy level. It can hold a maximum of two electrons.
2s and 2p subshells: The 2s and 2p subshells are the next energy level and can hold a maximum of eight electrons.
3s and 3p subshells: The 3s and 3p subshells are the next energy level and can hold a maximum of twelve electrons.
3d subshell: The 3d subshell is a type of subshell that can hold a maximum of ten electrons.
4s subshell: The 4s subshell is the outermost subshell and can hold a maximum of two electrons.

The Order of Increasing Energy

Now that we know about the subshells and their energy levels, we can determine the order of increasing energy for the subshells in a manganese atom. The order is as follows:

1s subshell: The 1s subshell has the lowest energy level and is filled first.
2s and 2p subshells: The 2s and 2p subshells are the next energy level and are filled next.
3s and 3p subshells: The 3s and 3p subshells are the next energy level and are filled next.
3d subshell: The 3d subshell is a type of subshell that can hold a maximum of ten electrons and is filled next.
4s subshell: The 4s subshell is the outermost subshell and is filled last.

The Electron Configuration of Manganese in Order of Increasing Energy

Based on the order of increasing energy, the electron configuration of manganese can be written as follows:

1s subshell: 1s²
2s and 2p subshells: 2s² 2p⁶
3s and 3p subshells: 3s² 3p⁶
3d subshell: 3d⁵
4s subshell: 4s²

Conclusion

In conclusion, the electron configuration of manganese can be written as 1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁵ 4s². The subshells that hold the 25 electrons in a manganese atom in order of increasing energy are the 1s subshell, the 2s and 2p subshells, the 3s and 3p subshells, the 3d subshell, and the 4s subshell. Understanding the electron configuration of an atom is essential in chemistry and is used to predict the properties and behavior of elements.
