Quick question about Aluminium ? How to find its oxidation state ?

In summary, the chemical symbol for Aluminium is Al. The oxidation state of Aluminium can be determined by looking at its position on the periodic table, with its most common state being +3. However, it can also have other states such as +1 and +2 in certain compounds. To find its oxidation state in a compound, the total charge of the compound can be equated to the sum of oxidation states of all elements, with Aluminium's state then being solved for. The oxidation state of Aluminium can be affected by the type of compound it is in, the presence of other elements, and the type of reaction it is involved in.

Homework Statement



I am struggling a bit with naming compounds.

Al2(Cr2O7)3

Now, I know its aluminum dichromate, and the way to find this was KNOWING the oxidation state of Al being +3 - How am I suppose to know that? How do you find that out when all you have is a basic periodic table?
