What is the history of the element aluminum?
Aluminum was first isolated in 1825 by Hans Christian Ørsted (Oersted) in Copenhagen, Denmark who reported, “a lump of metal which in color and luster somewhat resembles tin.” Ørsted produced aluminum by reducing aluminum chloride using a potassium-mercury amalgam. The mercury was removed by heating to leave aluminum.
When was aluminum discovered as an element?

Aluminium/Discoverers
How was aluminium first discovered?
In 1824, Danish physicist Hans Christian Ørsted attempted to produce the metal. He reacted anhydrous aluminium chloride with potassium amalgam, yielding a lump of metal that looked similar to tin. He presented his results and demonstrated a sample of the new metal in 1825.
Why is aluminum called aluminium?
In 1808, Sir Humphry Davy identified the existence of the metal in alum, which he at first named “alumium” and later “aluminum.” Davy proposed the name aluminum when referring to the element in his 1812 book Elements of Chemical Philosophy, despite his previous use of “alumium.” The official name “aluminium” was …
Was aluminum invented or discovered?
Discovery of this metal was announced in 1825 by Danish physicist Hans Christian Ørsted, whose work was extended by German chemist Friedrich Wöhler. Aluminium was difficult to refine and thus uncommon in actual usage. Soon after its discovery, the price of aluminium exceeded that of gold.
Where is the element aluminum found?
crust
Where is aluminum found on Earth? Aluminum is the third most abundant element and the most abundant metal found in the Earth’s crust. It is generally found on Earth in minerals and compounds such as feldspar, beryl, cryolite, and turquoise.
How many atoms are in the element aluminum?
Notice that aluminium is said to have an atomic mass of 26.982 u . The unit used here is the unified atomic mass unit, u . This means that the mass of one mole of aluminium atoms will be 26.982 g . As you know, one mole of any element contains exactly 6.022⋅1023 atoms of that element.
