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 is a native element as well as a mineral. Its crystal form consists of transparent to translucent crystals that have an unmistakable deep yellow color. In its massive form, the color is usually a pale yellow, but may sometimes be red or gray if impurities are present. Moisture in the air reacts with sulfur to release small amounts of hydrogen sulfide (H2S), giving sulfur a distinctive odor similar to rotten eggs.
