Tarihi
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.

Uygulamalar
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.
