INTRODUCTION
Magnesium is a malleable and ductile metal when heated and the lightest metal that remains stable under ordinary conditions With the exception of beryllium.It ranks eighth in natural abundance among elements in crustal rocks.
It has one funny property that when heated in air it reacts with oxygen and emits a brilliant white light, burning so hot that it will not be extinguished even if immersed in water.

ECONOMIC IMPORTANCE
* Magnesium is used extensively in making castings for airplane parts, in artificial limbs, vacuum cleaners, and optical instruments.
* It is used as dressing and filler for cotton and woolen fabrics, in paper manufacture, and in cements and ceramics.
* Magnesium citrate is formed by the reaction of magnesium carbonate with citric acid and is used in medicine and effervescent beverages.
* It used as a deoxidizer in the casting of metals, and as a getter, a substance that achieves final evacuation in vacuum tubes.
