In K2C2O4 (potassium oxalate) both potassium and carbon have positive oxidation states. Potassium's is 1+ and carbon's is 3+.
+2 oxidation state for the Copper. -1 for the Chloride
Under normal conditions, +2 is cadmium's only positive oxidation state.
This is a neutral compound. Na shows the +1 OXIDATION NUMBER.

Under normal conditions, +2 is cadmium's only positive oxidation state.
This is a neutral compound. Na shows the +1 OXIDATION NUMBER.
When the metal can exist in more than one oxidation state
Acetylene is a neutral compound.
The whole compound is seen to be neutral (0 oxidation state) as there are no ''-/+'' which indicate the overall charge of the compound. Although within almost all situations O has a -2 oxidation state. With this being now known and we know the whole compound is neutral (0) we can then see N must have the oxidation state of +2. 0 = (-2) + (+2)
The hydrogen atoms are each in the 1+ oxidation state. The oxygen is in it's 2- oxidation state.
Bromine is in +5 oxidation state, oxygen is -2 and sodium is +1.
