Fe2O3
Oxygen valence in all substances is 2
To find the valence of iron (Fe), you need to find the total valence of Oxygen in the substance.
How to do it?
It is necessary to multiply the amount of an element in a substance by the valence of this one element, that is:
Nzag = Nel * n, where Nzag is the total valence; Nel – valence of the element; n – number of elements
In our case, Nzag = 2 * 3 = 6. We found this through Oxygen
You can also find it through iron
Nzag = Nzh * nzh
6 = Nzh * 2
From this we find that the valence of iron in this substance is 3
The valence of Fe in Fe2O3 is 3
