Do you know the development history of magnesium? Here is a specific understanding:
Joseph Black identified magnesium as an element. He identified the bitter soil (magnesium oxide, MgO) in lime (calcium oxide, CaO), each of which is made by heating rocks similar to carbonate, magnesite, and limestone. Another magnesium mineral called sepiolite (magnesium silicate) was reported in 1799 by Thomas Henry, who said that this mineral was more commonly used in pipe making in Turkey.
The impure magnesium was first made in 1792 by Anton Rupprecht, who heated a mixture of bitter earth and charcoal. Pure but very small quantities of the metal were made by Humphry Davy in 1808 by electrolysis of magnesium oxide. However, it was the French scientist antoine-alexandre-brutus Bussy who prepared a considerable amount of the metal magnesium by the reaction of magnesium chloride and potassium in 1831, after which he began to study its properties.
Many centuries ago, the ancient Romans thought that magnesia, a white magnesium salt from the Greek region of magnesia, could cure many diseases. It was not until 1808 that the British chemist David used the method of electrolysis to separate the element magnesium. In the early 1930s, e. v. McCollum and his colleagues systematically observed the response to magnesium deficiency in rats and dogs for the first time. The first clinical report of a small number of cases of magnesium deficiency on a different disease basis was published in 1934. Confirm that magnesium is an essential element in the body.
Magnesium is one of the ten most widely distributed elements in nature (it is the eighth most abundant element in the earth's crust, accounting for about 2% of its mass, and the ninth most abundant element in the universe), but it has not been discovered because it is difficult to be reduced from compounds to elemental states.
For a long time, chemists treated the oxide leach of magnesium, obtained by roasting magnesite containing magnesium carbonate, as an indivisible substance. It is listed in the list of elements published by Lavoisier in 1789. In 1808, after successfully producing calcium, David succeeded in producing magnesium in the same way. Since then magnesium has been identified as an element and given the name "m", with the element symbol "m". Magnesium comes from the Greek city of Magnesia, which is called Magnesia alba, or white Magnesium oxide, for the element Mg, because Magnesium oxide is produced near this city. Magnesium has an atomic order of 12 and an atomic weight of 24.3. Due to the oxide properties of magnesium and calcium between "alkaline" and "earth", it is called alkaline earth metal elements.
