Magnesium is a chemical element; it has symbol Mg and atomic number 12. It is a shiny gray metal having a low density, low melting point and high chemical reactivity. Like the other alkaline earth metals (group 2 of the periodic table), it occurs naturally only in combination with other elements and almost always has an oxidation state of +2.

Mar 19, 2025 · magnesium (Mg), chemical element, one of the alkaline-earth metals of Group 2 (IIa) of the periodic table, and the lightest structural metal. Its compounds are widely used in construction and medicine, and magnesium is one of the elements essential to all cellular life.

Magnesium metal's principal use is as an alloying addition to aluminum; these aluminum-magnesium alloys are used mainly for beverage cans. Magnesium alloys also are used as structural components of automobiles and machinery.

May 15, 2023 · Magnesium is the lightest metal available, and when combined with other metals like aluminum and zinc, it creates alloys that are stronger and lighter than other materials. These alloys are commonly used in the manufacturing of airplanes, cars, and bicycles.

Jun 25, 2019 · Learn about magnesium, the lightest of the metal elements, used primarily in structural alloys due to its light weight, strength and corrosion resistance.

What is Magnesium. A silver-white tough metal, magnesium (pronounced as mag-NEE-zhi-eem) belongs to the family of alkali earth metals. Represented by the chemical symbol Mg, it burns easily in air with a distinctive bright white light [1, 2].

Magnesium is a silvery-white, low density, reasonably strong metal that tarnishes in air to form a thin oxide coating. Magnesium and its alloys have very good corrosion resistance and good high temperature mechanical properties.
