Discovery: 1808 Sir Humphry Davy (GB)

Magnesium was discovered by Sir Humphry Davy (GB) in 1808. The origin of the name comes from the Greek word 'Magnesia', a district of Thessaly. It is a lightweight, malleable, silvery-white metal that burns in air with a brilliant white flame and reacts with water as temperature elevates. It can ignite in air and it reacts violently with oxidants. Magnesium is found in large deposits in the form of magnesite, dolomite and other minerals. It is usually obtained by electrolysis of melted magnesium chloride (MgCl2) derived from brines, wells and sea water. Magnesium is used in alloys to make airplanes, missiles and other uses for light metals. It has structural properties similar to aluminium.
