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.

2024年12月21日 · 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.

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).

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.

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.

2009年6月16日 · Aluminium citrate is more soluble than many other aluminium compounds and is likely to be more bioavailable from drinking-water than from food. The Committee concluded that the NOAEL of 30 mg/kg bw per day was an appropriate basis for establishing a PTWI for aluminium compounds.

2005年5月17日 · 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.
