The element represented by the symbol C is carbon. Carbon is a nonmetal known for its unique ability to form stable bonds with many elements, including itself, resulting in a vast array of organic compounds. It is a fundamental building block of life, as it is an essential component of proteins, lipids, carbohydrates, and nucleic acids. Carbon exists in several allotropes, including graphite, diamond, and amorphous carbon. Its versatility in forming chemical bonds makes it crucial for both biological functions and industrial applications.
