Rules for assigning oxidation states 1 assigning oxidation states to organic compounds proceeds by a process of deduction, in which. Rules for assigning oxidation states the oxidation state (os) of an element corresponds to the number of electrons, e-, that an atom loses, gains, or appears to use when joining with other. Next, we see that o is more electronegative than n, hence we assign o with the lower oxidation state what is an oxidation number, or oxidation state.
