![]() It has been detected in the gas phase after explosion of aluminized grenades in the upper atmosphere and in stellar absorption spectra. Properties – Health effects of aluminum – Environmental effects of aluminum Atomic numberĪluminium(II) oxide or aluminium monoxide is a compound of aluminium and oxygen with the chemical formula AlO. What are the chemical properties of Aluminium? Element NameĪluminum monoxide | AlO – PubChem. It is an aluminium cation, a monoatomic trication and a monoatomic aluminium….4.3Related Element. What is the Ion name for aluminum?Īluminium(3+) is an aluminium cation that has a charge of +3. What is the chemical symbol of aluminium?Īluminum (Al), also spelled aluminium, chemical element, a lightweight silvery white metal of main Group 13 (IIIa, or boron group) of the periodic table. What is the molecular formula for aluminum and oxygen?.How much weight does Al2O3 lose in vacuum?.What are the chemical properties of Aluminium?.What is the chemical symbol of aluminium?.Most aluminum is extracted from a mineral called bauxite, which can be found in various places around the world but is mostly mined in Australia. This was learned during the 1960s and 1970s, when buildings constructed with aluminum wire began to catch fire with alarming frequency. It is not suitable for general purpose wiring, though, because terminations of aluminum wiring tend to work loose or develop an oxide film. It also competes with copper as the material of construction for busbars and high-capacity power cables. Its high thermal conductivity has led to widespread use in blocks and cylinder heads of internal combustion engines and in cookware.Īluminum has replaced copper as the material used for overhead power wiring. The properties of being lightweight, malleable, strong, and being seemingly "unreactive" (by its oxide layer) make it useful for things like aeroplanes, chip packets, and aluminum foil. It can be a cation (as an aluminum salt) or an anion (as aluminates, for example).Īluminum is a relatively cheap but useful metal.The metal itself is highly reactive, though its aluminum oxide layer gives aluminum its seemingly unreactive properties.Because of the abundance of these salts, the potential for a biological role for them is of continuing interest, and studies continue. In the 21st century, most aluminium was consumed in transportation, engineering, construction, and packaging in the United States, Western Europe, and Japan.ĭespite its prevalence in the environment, no living organism is known to use aluminium salts metabolically, but aluminium is well tolerated by plants and animals. In 1954, aluminium became the most produced non-ferrous metal, surpassing copper. In World Wars I and II, aluminium was a crucial strategic resource for aviation. Aluminium became much more available to the public with the Hall–Héroult process developed independently by French engineer Paul Héroult and American engineer Charles Martin Hall in 1886, and the mass production of aluminium led to its extensive use in industry and everyday life. The first industrial production of aluminium was initiated by French chemist Henri Étienne Sainte-Claire Deville in 1856. The discovery of aluminium was announced in 1825 by Danish physicist Hans Christian Ørsted. The strong affinity towards oxygen leads to aluminium's common association with oxygen in nature in the form of oxides for this reason, aluminium is found on Earth primarily in rocks in the crust, where it is the third most abundant element after oxygen and silicon, rather than in the mantle, and virtually never as the free metal. The aluminium cation Al 3+ is small and highly charged as such, it is polarizing, and bonds aluminium forms tend towards covalency. ![]() The radioactivity of 26Al is used in radiodating.Ĭhemically, aluminium is a weak metal in the boron group it forms compounds primarily in the +3 oxidation state, as is common for the group. It has one stable isotope, 27Al this isotope is very common, making aluminium the twelfth most common element in the Universe. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. ![]() In British literature the element's name is spelled alumin ium and the extra syllable pronounced: al - min - i - um.Īluminium ( aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. You can help Elements Wiki by expanding it.Īluminum a Post-Transition Metal and has a atomic number of 13.
