AL has various meanings in the Chemistry category. Discover the full forms, definitions, and usage contexts of AL in Chemistry.
A silver-white soft metal, noted for its lightness, high reflectivity, high thermal conductivity, non-toxicity and corrosion resistance. It is the most abundant metallic element, comprising about 1/12th of the earth's crust. It is never found in nature as an elemental metal, but only in combination with oxygen and other elements. In ordinary commercial and industrial use, the word "aluminum" is often understood to mean aluminum alloy, rather than the pure metal.
ChemistryA molecule with a hydroxyl group attached to a carbon atom. OR an organic chemical that contains an —OH group. OR "Any chemical compound where the hydroxy functional group -O-H is bound to an carbon skeleton. You are probably most familiar with the diols (compounds with two hydroxy groups), which are used in the manufacture of polyesters, and the phenols, where an hydroxy group is bound to an arene.
ChemistryAluminium or aluminum is a chemical element with symbol Al and atomic number 13. It is a silvery-white, soft, nonmagnetic, ductile metal in the boron group. By mass, aluminium makes up about 8% of the Earth's crust; it is the third most abundant element after oxygen and silicon and the most abundant metal in the crust, though it is less common in the mantle below.
