Now, we add an oxygen to one of those sulfurs. Oxygen is (almost) always -2. To keep the overall charge -2, that means that the newly bonded sulfur is oxidation state +1. Oxidizing that sulfur again gives sulfurs of +3 and -1. Finally, in thiosulfate the oxidations states are +5 and -1. Share.

Physical Properties of Sulfur. Sulfur has an atomic weight of 32.066 grams per mole and is part of group 16, the oxygen family. It is a nonmetal and has a specific heat of 0.706 J g -1 o C -1. The electron affinity is 200 kJ mol -1 and the electronegativity is 2.58 (unitless). As a result, sulfur forms many compounds that are analogs of oxygen compounds, as shown in the table below. Examples in this table show how the prefix thio- can be used to indicate compounds in which sulfur replaces an oxygen atom. The thiocyanate (SCN-) ion, for instance, is the sulfur-containing analog of the cyanate (OCN-) ion. Salt prevents bad bacteria from thriving—so how can it "go bad"?
