Aluminium carbonate (Al 2 (CO 3) 3), is a carbonate of aluminium.It is not well characterized; one authority says that simple carbonates of aluminium are not known. [2] However related compounds are known, such as the basic sodium aluminium carbonate mineral dawsonite (NaAlCO 3 (OH) 2) and hydrated basic aluminium carbonate minerals scarbroite (Al 5 (CO 3)(OH) 13 •5(H 2 O)) and ...
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
As an approximate rule, electron configurations are given by the Aufbau principle and the Madelung rule. However there are numerous exceptions; for example the lightest exception is chromium, which would be predicted to have the configuration 1s 2 2s 2 2p 6 3s 2 3p 6 3d 4 4s 2 , written as [Ar] 3d 4 4s 2 , but whose actual configuration given ...
Aluminium acetylacetonate, also referred to as Al(acac) 3, is a coordination complex with formula Al(C 5 H 7 O 2) 3. This aluminium complex with three acetylacetone ligands is used in research on Al-containing materials.
The only stable chalcogenides under normal conditions are aluminium sulfide (Al 2 S 3), selenide (Al 2 Se 3), and telluride (Al 2 Te 3). All three are prepared by direct reaction of their elements at about 1,000 °C (1,832 °F) and quickly hydrolyse completely in water to yield aluminium hydroxide and the respective hydrogen chalcogenide .

Tris(8-hydroxyquinolinato)aluminium is the chemical compound with the formula Al(C 9 H 6 NO) 3. Widely abbreviated Alq 3 , it is a coordination complex wherein aluminium is bonded in a bidentate manner to the conjugate base of three 8-hydroxyquinoline ligands .
Industrially, simple aluminium alkyls of the type Al 2 R 6 (R = Me, Et) are prepared in a two-step process beginning with the alkylation of aluminium powder: 2 Al + 3 CH 3 CH 2 Cl → (CH 3 CH 2) 3 Al 2 Cl 3. The reaction resembles the synthesis Grignard reagents. The product, (CH 3 CH 2) 3 Al 2 Cl 3, is called ethylaluminium sesquichloride ...
