Ninth most abundant element in the earth's crust (5700 ppm). It can be highly polished, and is relatively immune to tarnishing. Since it is strong and resists acids it is used in many alloys. Titanium dioxide (TiO2), a white pigment that covers surfaces very well, is used in paint, rubber, paper and many others. Usually occurs in the minerals ilmenite (FeTiO3) or rutile (TiO2). Also in Titaniferous magnetite, titanite (CaTiSiO5), and iron ores. Pure metal produced by heating TiO2 with C and Cl2 to produce TiCl4 then heated with Mg gas in Ar atmosphere. jA_TY_2gqZY Titanium
Scottish chemist Joseph Black recognized magnesium as an element in 1755.

Magnesium was first isolated by Sir Humphry Davy in 1808, in London.

He used electrolysis on a mixture of magnesia and mercuric oxide.

Antoine Bussy prepared it in coherent form in 1831. From Magnesia, district in Thessaly 22 1791 William Gregor England Named after the "Titans", (the sons of the Earth goddess in Greek mythology)

Because serious fires can occur, great care should be taken in handling magnesium metal
When it burns in air, magnesium produces a brilliant white light
Magnesium is widely used in the manufacturing of mobile phones, laptop computers, cameras, and other electronic components.

The brilliant light it produces when ignited is made use of in photography, flares, pyrotechnics and incendiary bombs.

Magnesium compounds such as the hydroxide (milk of magnesia), sulfate (Epsom salts), chloride and citrate are used for medicinal purposes.
