Instead, you should have asked, "How do I change an empirical formula into a chemical formula?"
To express the chemical formula of Al2Br6, we need to understand the valency of each element present in the compound.
Aluminum (Al) has a valency of 3, meaning it can form three chemical bonds.
Bromine (Br) has a valency of 1, meaning it can form one chemical bond.
Now, looking at the compound, we see that there are two aluminum atoms and six bromine atoms. To balance the charges and form a neutral compound, we need to combine the elements in a way that each element's valency is satisfied.
Since aluminum has a valency of 3 and bromine has a valency of 1, we can pair three bromine atoms with each aluminum atom to satisfy their valencies. This gives us the chemical formula:
Al2Br6
This means that the compound Al2Br6 consists of two aluminum atoms bonded to six bromine atoms.
