Magnesium Report My element is on magnesium. Magnesium has had a long history. It was discovered by Sir Humphrey Davy in England, 1755. A farmer noticed that water in a well healed scratches and rashes. The fame of Epsom salts spread. It was eventually recognized as magnesium sulphate. Black recognized magnesium as an element in 1755. It was isolated by Davy in 1808. Magnesium was named from the Greek word “ Magnesia”, a district of Thessaly. There are several ways magnesium is used. Magnesium is used in flares and protechnics, including incendiary bombs. It is used in alloys for aircraft, car engine castings and missile construction. The hydroxide (milk of magnesia), chloride, sulphate, and the citrate are all used in medicine. Magnesium oxide is used in bricks and liners in furnaces. Finally, it is used in computers for radio frequency shielding. There are several facts about magnesium. Magnesium is the eighth most abundant element in the earth’s crust, although pure magnesium does not occur in nature. It is the lightest metal strong enough to use in construction. It is lighter than aluminum. Magnesium is an important element in animal and plant life. The adult daily requirement of magnesium is about 0.3 grams. Finally, there are a lot of compounds contain magnesium. Some include magnesium dihydride (MgH2), magnesium diflouride (MgF2), magnesium dichloride (MgCl2), magnesium oxide (MgO), magnesium sulphide (MgS), magnesium selenide (MgSe), and magnesium telluride (MgTe). media type="custom" key="10776036" width="130" height="130"
