Formula of Aluminium oxide is Al2O3.
|Molar Mass||101.960 g·mol−1|
|Melting Point||2,072 °C|
|Boiling Point||2,977 °C|
The aluminium ions and oxygen ions have a charge. Aluminium has a positive charge of +3, while oxygen has a negative charge of -2. The formula for aluminium oxide is obtained by using the criss-cross process. In the chemical process, aluminium usually loses three electrons while oxygen gains two, which is performed primarily to achieve stability.
