Sulphur is a bright yellow, non-metallic element found in nature, often in volcanic regions and mineral deposits. It is essential for life and is a key component of amino acids, which are the building blocks of proteins. Sulphur is commonly used in fertilizers, helping plants grow by providing necessary nutrients. In addition to its agricultural uses, sulphur is important in various industrial processes. It is used to produce sulfuric acid, one of the most widely used chemicals in the world, and is also found in products like matches and fireworks. Its distinct smell, often compared to rotten eggs, comes from its compounds.
