Magnesium History

In 1808, the metal magnesium itself was first produced in England by Sir Humphry Davy using electrolysis of a mixture of magnesia and mercury oxide.
In 1831, Antoine Bussy prepared it in coherent form.
Davy's first suggestion for a name was magnium, but the name magnesium is now used.

Magnesium Specification

Magnesium, its cas register number is 7439-95-4. It also can be called EckaGranules PK 31; Ecka Granules PK 51; Magnesium element; Magnum Forte; Ozone magnez. Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a silver or grey rod, turnings or ribbon. The more finely divided material reacts with water to liberate hydrogen, a flammable gas, though this reaction is not as vigorous as that of sodium or lithium with water. In finely divided forms is easily ignited. It burns with an intense white flame and it can be wax coated to render magnesium as nonreactive.It slowly oxidizes in moist air. Reacts very slowly with water at ordinary temperatures, less slowly at 100 °C.

Preparation of Magnesium: Magnesium is principally obtained by electrolysis of fused magnesium chloride from brines, wells, and sea water. At the cathode, the Mg²⁺ ion is reduced by two electrons to magnesium metal:
Mg₂+ + 2 e− → Mg

Uses of Magnesium: Magnesium is the third most commonly used structural metal, following iron and aluminium. It has been called the lightest useful metal by The Periodic Table of Videos. The main applications of magnesium are, in order: component of aluminium alloys, in die-casting (alloyed with zinc), to remove sulfur in the production of iron and steel, the production of titanium in the Kroll process. The second application field of magnesium is electronic devices. Because of low weight, good mechanical and electrical properties, magnesium is widely used for manufacturing of mobile phones, laptop and tablet computers, cameras, and other electronic components.

When you are using this chemical, please be cautious about it as the following:
1. In case of fire, use ... (indicate in the space the precise type of fire-fighting equipment. If water increases the risk add - Never use water);
2. Keep container tightly closed and dry;
3. Wear suitable protective clothing;
4. Take precautionary measures against static discharges;
5. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice;

You can still convert the following datas into molecular structure:
