Magnesium : (noun)
1: a light silver-white ductile bivalent metallic element; in

dolomite and carnallite and spinel and olivine) [syn: Mg,
atomic number 12]

Magnesium : \Mag*ne"si*um\, n. [NL. & F. See Magnesia.] (Chem.)
A light silver-white metallic element, malleable and ductile,
quite permanent in dry air but tarnishing in moist air. It
burns, forming (the oxide) magnesia, with the production of a
blinding light (the so-called magnesium light) which is used
in signaling, in pyrotechny, or in photography where a strong
actinic illuminant is required. Its compounds occur
abundantly, as in dolomite, talc, meerschaum, etc. Symbol Mg.
Atomic weight, 24.4. Specific gravity, 1.75.
Magnesium sulphate. (Chem.) Same as Epsom salts.

Magnesium : Symbol: Mg
Atomic number: 12
Atomic weight: 24.312
Silvery metallic element belonging to group 2 of the periodic table
(alkaline-earth metals). It is essential for living organisms, and is used
in a number of light alloys. Chemically very reactive, it forms a
protective oxide coating when exposed to air and burns with an intense
white flame. It also reacts with sulphur, nitrogen and the halogens. First
isolated by Bussy in 1828.

Magnesium : Magnesium: A mineral involved in many processes in the body including enzymes are known to depend on magnesium.
Magnesium is contained in all unprocessed foods. High concentrations of magnesium are contained in nuts, unmilled grains, dark-green leafy vegetables, legumes such as peas and beans, and fruit.
Magnesium is thus readily available in foods that form the basis of a healthful diet.
larynx , etc.).
According to the food and water. Persons with impaired kidney function should be especially careful about their magnesium intake because they can accumulate magnesium, a dangerous situation.
Drinking water is a significant source of magnesium if the water supply is hard -- rich in minerals. (Water supplies in much of the US are hard but in the Southeast they are soft.) Soft water is
deficient in minerals, including magnesium. Water for drinking should therefore not be softened.
