The sharing of electrons brings a formal charge of +1 for one of the #Cl# atoms and a charge of -1 to the other #Cl# atom, bringing the overall charge/oxidation state to zero [(+1) + (-1)]. There are a few exceptions to this rule: When oxygen is in its elemental state (O 2), its oxidation number is 0, as is the case for all elemental atoms. This activity was created by a Quia Web subscriber. for the #Cl_2#: [(+1) + (-1)] = 0 (no charge) #Cl^+##Cl^-#.
