The answer on the mark scheme is +2, but i don't understand how you get to that. The terminal sulfurs, on the other hand, have no lone pairs, and all the electrons from the sulfur-oxygen bonds are assigned to oxygen, since it's the more electronegative element. In a neutral molecule, the sum of all the oxidation states should be zero. 2x + 2(-1) = -2. x = 0 Reduced sulfur compounds such as sulfide (H 2 S), thiosulfate (S 2 O 3 2 −), tetrathionate (S 4 O 6 2 −), and elemental sulfur (S 0) are used as the electron donors by sulfur oxidizers (Table 2). Its IUPAC name is 2-(dithioperoxy)disulfate, and the name of its corresponding acid is 2-(dithioperoxy)disulfuric acid. The two central sulfurs each have two lone pairs and are assigned half of the electrons from the two bonds they make, since the electrons of bonds between atoms of the same element must be distributed evenly (due to there being, by definition, an electronegativity difference of zero between two atoms of the same element). state of Na) + 4 (ox.
