Aluminium ( 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.
Aluminum is a chemical element with the atomic number 13 and the symbol Al. In the boron group, it is a silvery-white, soft, nonmagnetic, and ductile metal. Aluminum is the most prevalent metal and the third most abundant element in the earth’s crust after oxygen and silicon.
Aluminium is a silvery-white metal, the 13 element in the periodic table. One surprising fact about aluminium is that it's the most widespread metal on Earth, making up more than 8% of the Earth's core mass. It's also the third most common chemical element on our planet after oxygen and silicon.
May 30, 2024 · aluminum (Al), chemical element, a lightweight silvery white metal of main Group 13 (IIIa, or boron group) of the periodic table. Aluminum is the most abundant metallic element in Earth ’s crust and the most widely used nonferrous metal.

Jan 21, 2024 · Suppose you want to carry electricity over long distances from power plants to homes and factories. You could use copper, which is generally the best conductor (carrier) of electricity, but it's heavy and expensive. Aluminum might be an option, but it doesn't carry electricity so readily.
History of aluminium. Extrusion billets of aluminium in Yugoslavia, 1968. Aluminium (or aluminum) metal is very rare in native form, and the process to refine it from ores is complex, so for most of human history it was unknown. However, the compound alum has been known since the 5th century BCE and was used extensively by the ancients for dyeing.
