Question

Write the chemical formula of Aluminium oxide​

Answer 1

Answer:

Al²O³

Step-by-step explanation:

The formula of aluminium oxide is given as Al²O³. How is this formula generated? First of all, we have to consider that aluminium is a metal and Oxygen is a non-metal making it an ionic compound. There is some charge in the aluminium and oxygen ions. Aluminium has a +3 charge whereas oxygen has -2 charge. On applying the criss-cross method we get the formula of aluminium oxide. Usually, aluminium loses three electrons while oxygen gains two electrons in the chemical process and this is mainly to achieve stability.
