Magnesium is a member of the alkaline earth metals groups.
More Info: Magnesium is the second lightest element in its family. All of the alkaline earth elements are shiny metals with a silver-white color. All of the metals in this family are highly reactive and easily form oxides even at room temperature. Magnesium is so reactive it will even oxidize in a carbon dioxide. The distinctive bright white flame of magnesium cannot therefore be put out with common carbon dioxide fire extinguishers.
Magnesium is the only element in its group produced and used on a wide scale. It is most commonly extracted from sea water as magnesium hydroxide, which is purified to a chloride and then the pure metal. Magnesium is commonly used with aluminum to create a lightweight alloy used in aircraft production. The bright burning of magnesium is a quality used in flares and military devices. Some compounds of magnesium have such an extremely high melting point that they are used as lining in industrial furnaces.
Important Dietary Nutrient
Magnesium is also an important dietary nutrient. Most people do not consume enough magnesium. The best source of the nutrient is leafy green vegetables. It essential for the health of several organs and plays an important role in regulating the levels of other nutrients in the body.
