I can only assume what you are trying to ask in your question, but sulfur has an oxidation number of #8#, oxygen has an oxidation number of #-2# and hydrogen has an oxidation number of #1#.

Explanation:

In sulfuric acid, the molecular formula is #"H"_2"SO"_4#. Oxygen almost always has an oxidation number of #-2#, so #4# oxygen atoms means the charge is #8-#. Sulfur, in this case, has an oxidation number of #+6#, which means that #"SO"_4# ion has an overall charge of #2-#. Thus we need to hydrogen atoms to balance the charges.

As you can see, sulfur has donated six electrons, each oxygen atom has accepted two electrons and each hydrogen atom has donated one electron.
