magnesiummetal

Magnesium is a chemical element with the symbol Mg and atomic number 12. It is an alkaline earth metal, a light, silvery-white metal. Magnesium is the eighth most abundant element in the Earth's crust and the ninth in the universe. It is highly reactive and readily forms a black oxide layer when exposed to air. In its pure form, magnesium is quite malleable and ductile.

Magnesium is found in various compounds, notably in minerals like dolomite and magnesite, and dissolved in seawater. Its production involves electrolytic processes or reduction of magnesium oxide. The metal burns with a brilliant white light, a property that has led to its use in fireworks and flares.

Due to its low density and high strength, magnesium alloys are extensively used in the aerospace and automotive industries. These alloys offer a good strength-to-weight ratio, contributing to fuel efficiency. Magnesium is also vital for biological organisms. It is an essential mineral for all living cells, playing a role in over 300 biochemical reactions, including energy production, muscle and nerve function, and blood glucose control. Magnesium is also used in medicine, often as an antacid or laxative.
