Magnesium is a chemical element; it has symbol Mg and atomic number 12. It is a shiny gray metal having a low density, low melting point and high chemical reactivity. Like the other alkaline earth metals (group 2 of the periodic table) it occurs naturally only in combination with other elements and it almost always has an oxidation state of +2.
4 wrz 2024 · magnesium (Mg), chemical element, one of the alkaline-earth metals of Group 2 (IIa) of the periodic table, and the lightest structural metal. Its compounds are widely used in construction and medicine, and magnesium is one of the elements essential to all cellular life.
The first person to recognise that magnesium was an element was Joseph Black at Edinburgh in 1755. He distinguished magnesia (magnesium oxide, MgO) from lime (calcium oxide, CaO) although both were produced by heating similar kinds of carbonate rocks, magnesite and limestone respectively.
Magnesium is an ancient element and is characterized as an alkaline earth metal. it was discovered by Joseph Black in 1700s. It is a very light metal and can withstand high temperatures and is widely used in making electronics and appliances.
25 cze 2019 · History. Magnesium was discovered as a unique element in 1808 by Sir Humphrey Davy but not produced in metallic form until 1831 when Antoine Bussy made magnesium during an experiment with dehydrated magnesium chloride. Commercial production of electrolytic magnesium began in Germany in 1886.
2 sie 2007 · Magnesium was originally named 'magnium' by Humphrey Davy after isolating the element from magnesia, known now as magnesium oxide. The 1915 Nobel Prize in Chemistry was awarded to Richard Willstätter for his work with the chlorophyll and identifying magnesium was the central atom in its structure.
