SO2−4 has a total charge of −2, and oxygen is more electronegative than sulfur. So, oxygen polarizes the electron density towards itself more, and thus has the more negative oxidation state here. ⇒ x gives the oxidation state of sulfur, which is +6.
The oxidation number of the sulfur atom in the SO4 2 – ion must be +6, for example, because the sum of the oxidation numbers of the atoms in this ion must equal – 2.
For example, Na2SO4, Na2 yields 2 (plus 1) + 4(minus 2) = minus 6. Subtracting minus 6 from the neutral value of 0 yields 0 – (minus 6) = 6. This final value is the oxidation state of the unknown element, in this case sulfur.
The oxidation number of oxygen is almost always -2. For example, in sulfate ion (SO42-), each oxygen has an oxidation number of -2, whereas sulfur has an oxidation number of +6.
The oxidation number of each atom can be calculated by subtracting the sum of lone pairs and electrons it gains from bonds from the number of valence electrons. Bonds between atoms of the same element (homonuclear bonds) are always divided equally.
In general, most metals will have an oxidation equal to their charge when in ion form In the compound, ZnSO4 (aq), the oxidation number of the zinc ion (Zn2+(aq)) is +2.
S is +6. That last line Damon is showing that it checks out for S = +6 combined with -8 for the 4 O atoms leaves -2 for the SO4 ion as it should be.
So, two chromium atoms have an oxidation number of +12. So one chromium atom will have an oxidation number of +12 /2=+6. So oxidation number of Cr in K2Cr2O7 is +6. Was this answer helpful? Thank you.

Complete answer: So the oxidation state of acceptor sulphur atom is −2. And we have to find the oxidation state of another sulphur atom. Therefore the oxidation state of sulphur atoms in Na2S2O3 is −2 and +6.
