Chemical Properties of Magnesium

What is Magnesium?

• Magnesium is the most chemically active element. In boiling water, the place of hydrogen is taken by Magnesium and a number of metals can be produced using thermal reduction of its salts and oxidized forms with magnesium. We find Magnesium in the second group in the periodic table. We have been using Magnesium for a hundred years, in bonded form. It was only when a Chemist, Sir Humphry Davy purified and isolated the metal. Since it was found in the bonded form in nature, Magnesium took so long to isolate.
• Magnesium is labelled as the eighth most abundant element and about 2% of earth’s crust is constituted by Magnesium. In seawater, it is the most plentiful element present. It is found  in underground brines and salty layers. After aluminium and iron, magnesium is the third most abundant structural metal in the earth’s crust.
• Magnesium occurs naturally only in the combined form with other elements. The common oxidation state of Mg is +2. Magnesium can be prepared artificially and many alloys of magnesium are used for various purposes.

Uses of Magnesium

• Magnesium is used by scientists in medicine. It is used to treat widely in skin-related problems and attention deficit-hyperactivity disorder (ADHD), anxiety, mania, recovery after surgery etc.
• The green leafy vegetable is an excellent source of Magnesium. Whole grains, seeds, and nuts (mainly almonds) are also great sources of Magnesium.
• The flashbulbs also contain Magnesium. When Mg burns, it produces a bright light that helps  photographers to take photos in the dark.
