These sulfides are produced when things decay without air. Sulfur compounds are chemical compounds containing sulfur ions. Sulfur comes in several forms: oxidation states of -2 (hydrogen sulfide), +4 (sulfur dioxide, sulfites) and +6 (sulfuric acid, sulfates) are most common, although there are other oxidation states.
Sulfur: compounds information. This section lists some binary compounds with halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides), and some other compounds of sulfur. For each compound, a formal oxidation number for sulfur is given, but the usefulness of this number is limited for p-block elements in particular.
