Oxidation numbers are related to the polarity of the bond between two atoms. The basic rule is: The more electronegative atom gets ALL of the shared electrons. They end up with eight valence electrons each. Since they have each gained two electrons, their oxidation numbers are The C atom has no valence electrons.

Oxidation numbers are related to the polarity of the bond between two atoms. The basic rule is: The more electronegative atom gets ALL of the shared electrons. They end up with eight valence electrons each. Since they have each gained two electrons, their oxidation numbers are The C atom has no valence electrons. The sum of the oxidation numbers is zero.

The same principle holds for ions. This gives them eight valence electrons each, so their oxidation numbers are each The S atom is left with no valence electrons.

The sum of the oxidation numbers adds up to the overall charge on the ion What are oxidation numbers? Answer: This is formally the charge left on a central atom when all the bonding pairs of electrons are REMOVED, with the charge assigned to most electronegative atom Explanation: The rules for assignment of oxidation numbers are given here. And when we assign oxidation numbers, we use them to solve, i. And so we can interpret a given chemical reaction with the use of oxidation numbers.
