As the superoxide ion, O 2 –, oxygen has an oxidation state of –1/2. (b) The algebraic sum of all the oxidation numbers in a compound is zero. Since the overall charge must be zero one of them must have a positive charge and you always start with the most electronegative element and assign it the negative charge according to the rules on the chart. In this case, the oxygen has an oxidation state of +2. Moving to its positon, the sulfur atom is in group 16, it automatically gives us the valence number that also allows us to calculate the oxidation number. NCERT DC Pandey Sunil Batra HC Verma Pradeep Errorless.
