-2 for each O, +6 for S
If you mean SO3^-2 (the sulfite anion), then S has an oxidation number of 4+, since each O atom is 2-. In sulfur trioxide, SO3, the S atom has an oxidation number of 6+.
The oxidation state of an individual sulfur atom in (SO3)2- is 4.

SO3 is the chemical formula for sulfur trioxide.
If you mean SO3^-2 (the sulfite anion), then S has an oxidation number of 4+, since each O atom is 2-. In sulfur trioxide, SO3, the S atom has an oxidation number of 6+.
Things are complicated if we use the term valency. It is better to use the term Oxidation state or Oxidation Number. In SO2, the oxidation state of sulphur is +4 and In SO3, the oxidation state of sulphur is +6.
The oxidation state of an individual sulfur atom in (SO3)2- is 4.
SO3 = sulphur dioxide O2= oxygen SO3 = sulphur trioxide SO3- = sulphite that should be it .... right? :)

SO3 stands for Sulfur Trioxide.
No, SO3, sulphur trioxide is not a salt. A salt is an ionic compound such as might result from neutralizing an acid with a base. In SO3, there are no ions, and it is the result of oxidation.
sulfur and oxygen SO3
SO3 is the chemical formula for sulfur trioxide.
+6 oxidation state
It varies, dependent on the molecule. H2S ( Hydrogen sulphide ( -2) S ( sulphur) is (0) SO2 ( sulphurt dioxide is (4) SO3 ( sulphur trioxide is (6) These are the various oxidation state numbers. On the Pauling scale of electronegativity the value is 2.5
