A nonmetal, sulfur is the 10th most abundant element in the universe, according to the Jefferson National Linear Accelerator Laboratory. Today, it's most common use is in the manufacture of sulfuric acid, which in turn goes into fertilizers, batteries and cleaners.
Interestingly, sulfur is perhaps the most abundant element in the human body. It is found in most proteins in the sulfur-containing amino acids, along with phosphorus and nitrogen. These three elements form a triad of important elements needed as building blocks or structural components of all animal tissues.
