 * Symbol: S **
 * Atomic Number: 16 **
 * Mass: 32.06 **
 * At room temperature, Sulfur is extremely soft and a yellowish shade of solid color. The Sulfur then gives off a certain odor that resembles that of rotten eggs. This smell is because of the Hydrogen Sulfide. **
 * Sulfur is as a component of gunpowder. It is also used in the vulcanization process with natural rubber and fungicide. Sulfur also comes in handy when making phosphate fertilizers. Also, many sulfuric papers and other types of papers are made using sulfur and you may also helpful in bleaching dry fruits. **
 * Sulfur is urgent when it comes to the human body. If it was not for sulfur being around, many of us may not be as healthy as we are today. Sulfur is extremely essential to our lives. It is a minor factor of fats, body fluids, and skeletal materials. **
 * Sulfur has been around for a while. It was known in China since the 6th century. Naturally, the Chinese has referred to this element as “Brimstone”. During the 3rd century, the Chinese had discovered that “Brimstone” could be used and extracted from Pyrite. In the U.S., Sulfur was discovered in 1867, underground in the Louisiana and Texas areas. **
 * Sulfur is a rough, yellow and resembles the shape and hardness of a crystal. Sulfur gives off a very unpleasant scent that is compared to that of rotten eggs. This scent is so unpleasant that it is referred to, in the bible, the smell of hell. This smell is due to the Hydrogen Sulfide. This chemical is the most common smell you would encounter if you were to take a whiff of a sewage plant or the sewage system. **

 * Sulfur forms compounds in two oxidation states -2(sulfide, S2-), +4 (sulfide SO32-). It can combine with pretty much every element. **

 * __ Isotopes  __**
 * Sulfur has 18 isotopes. Only four of these 18 are stable. These four are the following: 32S (95.02%), 33S (0.75%), 34S (4.21%), and 36S (0.02%). All of these radioactive isotopes of Sulfur, unfortunately, are very short lived, excluding 35S. This one of a kind isotope has a 174 day life-spand. **

 * Sulfur, by itself is a yellowish type of powder, but when mixed with sand, it forms more of a solid rock shape. Another interesting fact about Sulfur is that it is used to clean up mercury. If you were to drop a thermometer on the floor, all you would have to do is spread a little sulfur over the mercury and it mixes and cleans it up. **
