বিষয়ে Carbon
Carbon is a nonmetal that can form four covalent bonds, giving it extraordinary versatility in chemistry. It exists in several allotropes including diamond, graphite, graphene, and fullerenes. Carbon is the fourth most abundant element in the universe by mass. The carbon cycle is fundamental to life on Earth.
Uses & Applications
Steel production, plastics, fuels, carbon fiber composites, diamonds for cutting tools, activated charcoal, and graphite for pencils.
মজা কথা
Carbon forms nearly 10 million known compounds -- more than all other elements combined.
