Aluminium - 13Al: compounds information
This section lists some binary compounds with halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides), and some other compounds of aluminium. For each compound, a formal oxidation number for aluminium is given, but the usefulness of this number is limited for p-block elements in particular. Based upon that oxidation number, an electronic configuration is also given but note that for more exotic compounds you should view this as a guide only.
In compounds of aluminium (where known), the most common oxidation numbers of aluminium are: 3.
