Answer:

The oxidation number of ANY element is #0#.

Explanation:

As the element, sulfur has neither been reduced nor oxidized; it still possesses 6 valence electron. Of course, in sulfates, #SO_4^(2-)#, and sulfites, #SO_3^(2-)#, the sulfur atom assumes formal oxidation states of #VI+#, and #IV+#; in sulfides #-II#. What are the 2 oxidation states (or the average oxidation states if you like) of sulfur in #S_2O_3^(2-)#, thiosulfate ion?
