A carbon atom is a fundamental building block of life and is represented by the chemical symbol C. It has six protons, six neutrons, and six electrons, which allows it to form stable bonds with many other elements. This unique ability makes carbon essential for the formation of various organic compounds, including carbohydrates, proteins, and fats. Carbon can exist in different forms, known as allotropes, such as diamond and graphite. These allotropes have distinct physical properties due to the arrangement of carbon atoms. The versatility of carbon is crucial in chemistry, biology, and materials science, making it a key element in numerous applications.
