Chemistry Electrochemistry Oxidation Numbers. By assigning oxidation numbers to the atoms of each element in a redox equation, we can determine which element is oxidized and which element is reduced during the reaction. Post by Chem_Mod » Tue Aug 23, 2011 12:40 am . Oxidation numbers are theoretical charges on individual atoms. We can assign electrons to a bonded atoms, compare that number to the number in the outer shell of the unbonded atoms, and see if there is an excess or lack. The oxidation number of fluorine is always –1. Here is the full equation: SO4-2 + 2 CH2O + 2H > H2S + 2CO2 + 2H2O If the element gains electron, it will attain a negative oxidation state and if the element looses electrons, it will attain a positive oxidation state. , bromine, and oxidation number of co2 usually have an oxidation number of C CH.
