Alkaline earth metal Joseph Black recognized magnesium as an element in 1755. It was isolated by Sir Humphry Davy (1778-1829) in 1808 almost 200 years after its discovery. He electrolysised mixture of magnesia (magnesium oxide, MgO) and mercuric oxide (HgO). Davy's first suggestion for a name was magnium but the name magnesium is now used.

Georges Claude Although he proposed the use of liquid oxygen in iron smelting as early as 1910, his suggestion was not adopted until after World War II. While studying the inert gases, Claude found that passing electrical current through them produced light, and in 1910 he developed the neon lamp for use in lighting and signs.

Magnesium: historical information In 1618 a farmer at Epsom in England attempted to give his cows water from a well. This they refused to drink because of the water's bitter taste. However the farmer noticed that the water seemed to heal scratches and rashes. The fame of Epsom salts spread. Eventually they were recognised to be magnesium sulphate, MgSO 4.

Magnesium - Mg Magnesium. Chemical element, metallic, symbol Mg, situated in group IIa in the periodic table, atomic number: 12, atomic weight: 24,312. Magnesium is silvery white and very light. Its relative density is 1,74 and it’s density 1740 kg/m 3 (0.063 lb/in 3 or 108.6 lb/ft 3).Magnesium is known for a long time as the lighter structural metal in the industry, due to it’s low weight and to it’s capability of forming mechanically resistant alloys.agnesium in the environment. Magnesium is the eighth most abundant element and constitutes about 2% af the Earth's crust by weight, and it is the third most plentiful element dissolved in seawater.

- In 1899, a Swedish scientist named Waldemar Jungner invented the nickel–cadmium battery, a rechargeable battery that had nickel and cadmium electrodes in a potassium hydroxide solution; the first battery to use an alkaline electrolyte.It was commercialized in Sweden in 1910 and reached the United States in 1946.his was known as the trough battery. Volta himself invented a variant that consisted of a chain of cups filled with a salt solution, linked together by metallic arcs dipped into the liquid. This was known as the Crown of Cups. These arcs were made of two different metals (e.g., zinc and copper) soldered together.

Benjamin Franklin and the Discovery of Electricity 1600s | 1700s | 1800’s. Benjamin Franklin was one of most innovative Americans of all time. In deed, his work and experiments resulted in several important discoveries and inventions including electricity, bifocal glasses, a usable battery and many more. Ben Franklin believed electricity could be harnessed from lightning. In 1752, he devised an experiment to test his theory. Although details of the experiment remain sketchy to this day, Franklin originally wanted to test his theory atop a spire that was to be built on a Philadelphia church.

Magnesium Metal Magnesium is an alkaline earth metal that has the symbol Mg in the periodic table of elements. Magnesium is a fairly strong, silvery-white, light-weight metal (one third lighter than aluminum) that slightly tarnishes when exposed to air. In a powder, this metal heats and ignites when exposed to moisture and burns with a white flame.

- On This Day – June 11 : The Scottish chemist Joseph Black discovered carbon dioxide on this day in 1754. Description. Black noticed that upon heating, calcium carbonate (CaCO3) produced a gas that was denser than air and could not sustain fire or animal life. He called this gas ‘fixed air’, but we now know it as carbon dioxide (CO2).

Johann Rudolf Glauber Johann Rudolf Glauber (10 March 1604 – 10 March 1670) was a German-Dutch alchemist and chemist. Some historians of science have described him as one of the first chemical engineers. His discovery of sodium sulfate in 1625 led to the compound being named after him: Glauber's salt.e worked first manufacturing mirrors and later for two periods as Apothecary to the court in Giessen, the second time as the Chief Apothecary, leaving because of the Thirty Years War. In Amsterdam he built up a business manufacturing pharmaceuticals (including chemicals such as Glauber's salt).

Magnesium Deficiency and Alcoholism Magnesium Deficiency Found Among Alcoholics. The earliest account of clinical magnesium deficiency was initially reported way back in 1934. It was in 1954 when Flink reported alcoholism as a cause of magnesium deficiency. The deficiency of Magnesium was found to be widely prevalent among alcoholics. Based on studies conducted on animals, the magnesium deficiency is aggravated by the hepatic damage primarily caused by the intake of alcohol.

Explosively formed projectile Munroe effect and close relatives. Franz von Baader, in 1792 or 1799, discovered the process of explosive engraving, but this could not have been explosive forming in the modern sense, because he worked with black gunpowder, the detonation velocity of which is too low for what is generally called the Munroe effect.
