Magnesium By: Madison Matthews

About the Metal

The metal is called magnesium and its atomic number is 12. The atomic mass is 24.305 amu. This metal is a Alkaline Earth Metal.

Properties of This Metal

A chemical property is it is highly flammable. Especially when powdered or shaved into thin strips, though it is difficult to ignite in mass or bulk. Magnesium is a silvery white metal. The surface of magnesium metal is covered with a thin layer of oxide that helps protect the metal from attack by air. A physical property is the density. The density of magnesium is 1.738 g/mL, which means the metal will sink in water, but it is still relatively light weight. Elemental magnesium is a gray-white lightweight metal, two-thirds the density of aluminium. Another physical property is its melting point is 650 Celsius.

Where it is Found

Magnesium is the eighth most abundant element in the earth's crust but does not occur uncombined in nature. It is found in abundance in the minerals brucite, magnesite, dolomite, and carnalite. It is also found (as the silicate) in asbestos, meerschaum, serpentine, and talc.

What It is Used In On Earth

Magnesium is used in super-strong, lightweight materials and alloys. For example, when infused with silicon carbide nanoparticles, it has extremely high specific strength. It is also use in electronics, because of low weight and good mechanical and electrical properties, magnesium is widely used for manufacturing of mobile phones, laptop and tablet computers, cameras, and other electronic components. It is also combined with other metal to make racing bicycles, airplanes and other stuff that need to be light weight. Spices, nuts, cereals, cocoa and vegetables are rich sources of magnesium. Green leafy vegetables such as spinach are also rich in magnesium

These products are also made of magnesium.
