Aluminium (or aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals, about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.

Dec 21, 2024 · British chemist Sir Humphry Davy had prepared (1809) an iron-aluminum alloy by electrolyzing fused alumina (aluminum oxide) and had already named the element aluminum; the word later was modified to aluminium in England and some other European countries.

Aluminum (in British English: Aluminium) is a chemical element. The symbol for aluminum is Al, and its atomic number is 13. aluminum is the most abundant metal. It is a mononuclidic element.

No, the difference is merely regional with 'aluminum' favored by Americans and Candians, and 'aluminium' being used everywhere else. Both aluminum and aluminium have a long history of use referring to the metallic element (commonly used as foil to cover food).

The element was known in prehistoric times. In 1825, the Danish physicist, Hans Christian Oersted, isolated impure aluminium. The pure metal was first isolated by the German chemist Friedrich Wöhler in 1827.

Aluminium, or Aluminum in American spelling, is an ancient metal and has a diverse range of uses. It was discovered in 1824 and its light weight, high electrical conductivity and high resistant to corrosion has make it an industrially attractive metal.

In complex ions or molecules, Aluminium often adopts an octahedral geometry, with six atoms, ions, or molecules surrounding the central Aluminium atom. However, tetracoordinated and pentacoordinated Aluminium complexes also exist.

1 day ago · U.S. President Donald Trump said on Sunday he will introduce 25% tariffs on all steel and aluminum imports into the United States, on top of existing metals duties, in another major escalation of ...

Jan 21, 2024 · In short, you'd probably come up with a material like aluminum (spelled aluminium in some countries—and that's also the official IUPAC spelling). It's the commonest metal in Earth's crust (making up ~8 percent of it), the third most plentiful chemical element on our planet (only oxygen and silicon exist in greater quantity), and the second ...
