Sulfur is a nonmetallic element with various forms and compounds used in many industries and found in all living organisms. It has different ions, and its spelling varies. Sulfur is odorless and has many applications, including gunpowder, insecticides, and prescription drugs. It can be found in nature and is generally safe to handle, but some of its compounds are toxic.
Sulfur is a nonmetallic chemical element that appears in numerous forms and compounds. It is widely used in many industries, as are its ions, such as sulfides and sulfates. In addition to having industrial applications, sulfur is also an important part of all living organisms, and is even used as a food source by some bacteria, such as those found around hydrothermal vents.
In the periodic table of elements, sulfur is identified by the symbol S. The element has an atomic number of 16 and a number of different ions. An ion is a form of an element that has gained or lost electrons, changing the chemical structure and electrical charge of the element. Many consumers are familiar with sulfites, sulfur ions that are used in the preservation of many food products. Sulfates, another common ion, are used in a number of applications.
There is some dispute over the spelling of sulfur. In the United States, and many other countries, the word is “sulphur.” In nations using British English, the name is more commonly written as sulfur. While both spellings are recognized as correct, “sulphur” is actually more etymologically correct, reflecting the Latin roots of the word. In an effort to standardize spelling, most chemists try to use an “f.”
In pure form, sulfur has a number of allotropes. Allotropic elements are elements that can have a number of pure structures; Carbon is a well-known allotropic element, which occurs in both the form of diamonds and coal. Most allotropes of sulfur have a crystalline structure, although one is more plastic in nature. The best known is presented in yellow crystalline form, odorless and also rather fragile. Many people are surprised to learn that sulfur is odorless; the rotten egg smell associated with this element is actually hydrogen sulfide, a dangerous sulfur compound.
The highly reactive element is used in a number of applications including the manufacture of gunpowder, insecticides and prescription drugs. It is also part of the rubber vulcanization process and is the basis for well-used compounds such as sulfuric acid. In nature, sulfur can be found in compounds such as galena and cinnabar, and it can also appear in pure deposits, especially around volcanoes and mineral springs.
Sulfur itself is generally safe to handle, but many of its compounds are riskier. Some are extremely toxic and people should always be careful to follow the listed precautions of chemicals such as sulfur dioxide.
