Description
An alkaline earth metal that is one of the most common elements in the earth's crust at 2.1% by weight. Magnesium is found naturally in the following minerals: magnesite, carnallite, dolomite, epsomite, and kieserite. Magnesium salts are also dissolved in seawater. Magnesium was first isolated in metallic form by Sir Humphrey Davy in 1808. The lightweight silvery metal oxidizes slowly in moist air. Magnesium is used for the manufacture of lightweight metallic alloys, fireworks, flashbulbs, optical mirrors. Magnesium salts are used as heat-resistant and insulating materials and as fillers in paper, cements, ceramics, glass, and paint.
