Carbon is a very important non-metal that forms a huge variety of compounds. Its special ability to form four covalent bonds and to join with other carbon atoms makes possible long chains, branches, and rings. This is why carbon compounds are found in living things, fuels, medicines, and many everyd
Key Concepts
Carbon belongs to Group 14
Carbon belongs to Group 14, has electronic configuration 2,4, and valency four. It forms covalent bonds because it cannot easily gain or lose four ele
