When act as an oxidising agent ultimately forms
the number of electrons transferred in each case are:
4,3,1,5
1,5,3,7
1,3,4,5
3,5,7,1
As we learnt in
Rules for Oxidation Number -
In free or uncombined state, each atom bears an oxidation number of zero.
- wherein
e.g. H2, O2, Cl2, O3, P4, S8, Na, Mg, Al, etc.
Let's take the species individually
