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

Mar 28, 2025 · 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.

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

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.

May 17, 2005 · Aluminium is the world’s most abundant metal and is the third most common element comprising 8% of the earth’s crust. The versatility of aluminium makes it the most widely used metal after steel.

Aluminum is the second most abundant metallic element in the Earth's crust after silicon, yet it is a comparatively new industrial metal that has been produced in commercial quantities for just over 100 years.

Element Aluminium (Al), Group 13, Atomic Number 13, p-block, Mass 26.982. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images.

Aluminum naturally produces a thin oxide covering that protects the metal from further interaction with the environment. Aluminum alloys are less corrosion resistant than pure Aluminium except for marine magnesium-aluminum alloys. Aluminum is a good conductor of heat and electricity.

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.

Apr 15, 2023 · Aluminium is the most prevalent metallic element in the Earth’s crust (8.23% by mass) and the third most plentiful element overall (after oxygen and silicon). Aluminium is found in a wide range of silicates in the Earth’s crust. The Earth’s mantle, on the other hand, is only 2.38% aluminum by mass.
