The compounds of magnesium are quite stable. The melting temperature of magnesium is 651 ☌ and its boiling point is 1100 ☌. Magnesium can easily be molded, shaped, bend and cut and can be turned into various useful products in ways other metals cannot be used. The density of magnesium is 1.738 grams per cubic centimeter. The atomic number of magnesium is 12 and its atomic mass is 24.305. Magnesium belongs to the Group 2 (IIA) of periodic tables which makes it one of the alkaline earth elements. It has an atomic mass of 24.305 and atomic number of 12. Magnesium is unique as it has lightest weight as compared to all other metals. Magnesium is a silvery-white metal and is moderately hard. ![]() Naturally magnesium is also present in green vegetables, cereals, nuts and seafood. In US, the three main source of magnesium include mines (North Carolina), brine (Utah) and seawater (Texas, Florida). Turkey is ranked as the largest producer of various ores of magnesium, followed by Russia, China, North Korea and Austria. Other naturally occurring minerals of magnesium include dolomite (magnesium carbonate), and carnallite (potassium magnesium chloride). The most commonly known natural compounds of magnesium include Epsom salt (magnesium sulphate), and Dolomite (calcium magnesium carbonate). Magnesium occurs in the form of various compounds in the Earth and are quite abundant (around 60 naturally occurring compounds). About six million tons of magnesium are present per cubic mile of seawater. It is also present in oceans in dissolved form. Magnesium is the 8 th most abundant element in the crust of the Earth (2.1%). The term magnesium for this element have also been known since centuries and is selected in relation of a region, Magnesia, in Greece as large natural reserves of magnesium are present in this area. The pure form of magnesium was isolated in 1808 by Humphry Davy (English chemist) by passing current through magnesium oxide (molten form). ![]() In 1700s, various experimental studies were done on magnesium and Joseph Black reported various traits of magnesium and led to the formal discovery of this metal. Use of magnesium sulphate have been known since 1618, in Epsom town, England. Discovery and HistoryĪncient evidence of the use of magnesium by humans have been reported. ![]() It is a very light metal and can withstand high temperatures and is widely used in making electronics and appliances. it was discovered by Joseph Black in 1700s. Magnesium is an ancient element and is characterized as an alkaline earth metal.
