Magnesium - An Overview

Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a shiny, grey, strong metal that is known for its low density and high strength-to-weight ratio. Magnesium is the eighth most abundant element in the Earth's crust and is essential for living organisms.

Physical and Chemical Properties of Magnesium:

Atomic number: 12
Atomic mass: 24.305 u
Physical state at room temperature: Solid
Melting point: 650°C (1,202°F)
Boiling point: 1,090°C (1,994°F)
Density: 1.738 g/cm³
Chemical properties: Magnesium is highly reactive and can burn in air with an intense white light. It readily forms compounds with other elements, and is an essential component in many minerals.

Uses of Magnesium:

Magnesium has a wide range of industrial and biological uses, including:

Alloying agent in the production of aluminum-magnesium alloys, which are lightweight and strong
As a reducing agent in the production of titanium, zirconium, and other metals
In the production of magnesium-based materials such as magnesium oxide and magnesium hydroxide
In the manufacturing of fireworks, flares, and incendiary devices due to its ability to burn brightly
In medicine, as a supplement to support bone health and as a laxative
