Another Broken Egg Cafe Jobs, 1. Tutorial 6a 1. __gaTracker('send','pageview'); oxidation state of an element is it's no. the formal charge on the C in C6H12O6 (which is glucose by the way) is zero. Since the total is zero, which is the value of the oxidation number corresponding to a neutral molecule, the values are verified. According to rule 4, the sum of the oxidation number on all atoms must equal the charge on the species, so we have the simple algebraic equation. [CDATA[ */ The oxidation state of an atom in a molecule is the sum of all such effects resulting from bonding, plus the formal charge possibly present on the atom. Using the same example reaction as in Pete Gannett’s answer, CH4 + Cl2 → CH3Cl + HCl The oxidation number of C in CH4 is -4, and in CH3Cl is -2.
