The chemical element associated with the atomic number 6 is carbon. Carbon is a fundamental building block of life, found in all known biological organisms. Its unique ability to form four covalent bonds with other atoms enables the creation of a vast array of organic molecules, including proteins, carbohydrates, and nucleic acids. Carbon exists in various allotropes, such as graphite, diamond, and fullerene, each exhibiting distinct physical properties. It is also a vital component of fossil fuels and is integral to many industrial processes. In addition to its biological significance, carbon's role in climate change and global warming has brought it to the forefront of environmental discussions.
