Magnesium (Mg) is a chemical element with the atomic number 12 and the atomic mass 24.3050 u. It is a soft, silvery-white, alkaline earth metal that belongs to the second group of the periodic table. The electronic configuration of magnesium is $1s^2 \ 2s^2 \ 2p^6 \ 3s^2$ , which indicates that it has two electrons in the 1s orbital, two electrons in the 2s orbital, six electrons in the 2p orbital, and two electrons in the 3s orbital.

Atomic Structure of Magnesium

The atomic structure of magnesium consists of two main parts: the core electrons and the valence electrons. The core electrons are the electrons that are present in the inner shells of the atom, while the valence electrons are the electrons that are present in the outermost shell of the atom.

Core Electrons:

The core electrons of magnesium are the electrons that are present in the inner shells of the atom. These electrons are tightly bound to the nucleus and do not participate in chemical bonding. The core electrons of magnesium are:

$\square$

Valence Electrons:

The valence electrons of magnesium are the electrons that are present in the outermost shell of the atom. These electrons are responsible for the chemical properties of magnesium and participate in chemical bonding. The valence electrons of magnesium are:

$\square$

Chemical Properties of Magnesium

Magnesium is a highly reactive metal that readily loses two electrons to form a +2 ion. This makes it a highly reactive element that can easily react with other elements to form compounds. Some of the common chemical properties of magnesium include:

High reactivity: Magnesium is a highly reactive metal that readily loses two electrons to form a +2 ion.
High melting point: Magnesium has a high melting point of 650°C, which makes it a useful material for high-temperature applications.
High density: Magnesium has a high density of 1.74 g/cm³, which makes it a useful material for applications where high density is required.
High strength-to-weight ratio: Magnesium has a high strength-to-weight ratio, which makes it a useful material for applications where high strength is required.

Uses of Magnesium

Magnesium is a versatile element that has a wide range of applications. Some of the common uses of magnesium include:

Alloys: Magnesium is used to make alloys with other elements such as aluminum, zinc, and copper. These alloys are used in a wide range of applications including aircraft, automotive, and construction.
Fireworks: Magnesium is used in fireworks to produce a bright white light.
Photography: Magnesium is used in photography to produce a bright white light.
Medical applications: Magnesium is used in medical applications such as in the treatment of magnesium deficiency and in the production of magnesium-based pharmaceuticals.

Environmental Impact of Magnesium

Magnesium is a relatively environmentally friendly element that has a low toxicity and a low environmental impact. However, the extraction and processing of magnesium can have a negative impact on the environment. Some of the environmental impacts of magnesium include:

Water pollution: The extraction and processing of magnesium can lead to water pollution through the release of heavy metals and other pollutants.
Air pollution: The extraction and processing of magnesium can lead to air pollution through the release of particulate matter and other pollutants.
Soil pollution: The extraction and processing of magnesium can lead to soil pollution through the release of heavy metals and other pollutants.

Conclusion

Magnesium is a highly reactive element that has a wide range of applications. It is a versatile element that can be used in a wide range of applications including alloys, fireworks, photography, and medical applications. However, the extraction and processing of magnesium can have a negative impact on the environment. Therefore, it is essential to use magnesium in a responsible and sustainable manner to minimize its environmental impact.
