How was magnesium first discovered?
It was first isolated in 1808 by Sir Humphry Davy, who evaporated the mercury from a magnesium amalgam made by electrolyzing a mixture of moist magnesia and mercuric oxide. The name magnesium comes from Magnesia, a district of Thessaly (Greece) where the mineral magnesia alba was first found.

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.

How did Joseph Black Discover magnesium?
He found that with acids, magnesia alba behaved in a similar way to chalk (calcium carbonate), giving off a gas. He then heated a sample of the starting compound and found that the product, magnesia usta (now known as magnesium oxide), like quicklime (calcium oxide), did not effervesce with acids.
Where did Joseph Black Discover magnesium?
Edinburgh History. 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.
