Aluminium oxide (or aluminium(III) oxide) is a chemical compound of aluminium and oxygen with the chemical formula Al 2 O 3. It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium oxide. It is commonly called alumina and may also be called aloxide, aloxite, or alundum in various forms and ...
Aluminium forms one stable oxide with the chemical formula Al 2 O 3, commonly called alumina. [15] It can be found in nature in the mineral corundum, α-alumina; [16] there is also a γ-alumina phase. [13]
Aluminium(II) oxide or aluminium monoxide is a compound of aluminium and oxygen with the chemical formula AlO. It has been detected in the gas phase after explosion of aluminized grenades in the upper atmosphere [1] [2] [3] and in stellar absorption spectra. [4] Aluminium(II) oxide is one of the aluminium oxides (the most common is Aluminium ...

Aluminium chloride, also known as aluminium trichloride, is an inorganic compound with the formula AlCl 3. It forms a hexahydrate with the formula [Al(H 2 O) 6 ]Cl 3 , containing six water molecules of hydration .
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 .
The compound hydrogen chloride has the chemical formula HCl and as such is a hydrogen halide. At room temperature, it is a colorless gas, which forms white fumes of hydrochloric acid upon contact with atmospheric water vapor. Hydrogen chloride gas and hydrochloric acid are important in technology and industry.
A molecular formula enumerates the number of atoms to reflect those in the molecule, so that the molecular formula for glucose is C 6 H 12 O 6 rather than the glucose empirical formula, which is CH 2 O. However, except for very simple substances, molecular chemical formulae lack needed structural information, and are ambiguous.
