5. More Info
Magnesium is the eighth most abundant element in the earth's crust although not found in it's elemental form. It is a Group 2 element (Group IIA in older labeling schemes). Group 2 elements are called alkaline earth metals.
Magnesium tarnishes slightly in air, and finely divided magnesium readily ignites upon heating in air and burns with a dazzling white flame. Normally magnesium is coated with a layer of oxide, MgO, that protects magnesium from air and water.

6. Here’s A Little More!

7. The picture above shows the result of setting off a mixture of magnesium metal with solid silver nitrate with water! Do not attempt this reaction unless are a professionally qualified chemist and you have carried out a legally satisfactory hazard assessment. Select a movie icon to see the result of setting off a mixture of magnesium metal and solid silver nitrate with water!

9. Magnesium metal burns with a very bright light
Magnesium metal burns with a very bright light. The picture above shows the colour arising from adding magnesium powder to a burning mixture of potassium chlorate and sucrose. Do not attempt this reaction unless are a professionally qualified chemist and you have carried out a legally satisfactory hazard assessment.
Magnesium is an important element for plant and animal life. Chlorophylls are porphyrins based upon magnesium. The adult human daily requirement of magnesium is about 0.3 g day-1.

10. Isolation Of Magnesium
Magnesium can be made commercially by several processes and would not normally be made in the laboratory because of its ready availability. There are massive amounts of magnesium in seawater. This can be recovered as magnesium chloride, MgCl2 through reaction with calcium oxide, CaO.
CaO + H2O Ca2+ + 2OH-
Mg2+ + 2OH- Mg(OH)2
Mg(OH)2 + 2HCl MgCl2 + 2H2O
Electrolysis of hot molten MgCl2 affords magnesium as a liquid which is poured off and chlorine gas.
cathode: Mg2+(l) + 2e- Mg anode: Cl-(l) 1/2Cl2 (g) + e-
The other methods used to produce magnesium is non electrolytic and involves dolomite, [MgCa(CO3)2], an important magnesium mineral. This is "calcined" by heating to form calcined dolomite, MgO.CaO, and this reacted with ferrosilicon alloy.
2[MgO.CaO] + FeSi 2Mg + Ca2SiO4 + Fe
The magnesium may be distilled out from this mixture of products.
