Elemental sulfur is a bright yellow, non-metallic chemical element with the symbol S and atomic number 16. It is commonly found in nature, often near volcanic regions and hot springs, and is a key component of many minerals. Sulfur is essential for life, as it is a part of amino acids and proteins. In its pure form, elemental sulfur is odorless, but it can produce a strong smell when it combines with other elements, such as in sulfur dioxide from burning fossil fuels. Sulfur is widely used in industries, including the production of fertilizers, chemicals, and pharmaceuticals.
