A carbon atom is a basic unit of matter that is essential for life. It consists of six protons, six neutrons, and six electrons. The arrangement of these particles allows carbon to form strong bonds with other elements, making it a key component in many compounds, including organic molecules that are vital for living organisms. Carbon is unique because it can bond with itself and other elements in various ways, leading to a vast array of structures. This versatility is the foundation of organic chemistry, which studies the compounds primarily made of carbon, and is crucial for understanding biological processes.
