Question

Carbon is one of the ninety elements found in nature. However, together with hydrogen, it
is a special element found in the structure of all living things. Graphite is one of the three main
allotropic forms of carbon, formed in horizontal layers and is a carbon-based material with a
wide range of uses. Diamond, graphite, graphene and fullerenes are the allotrope of the carbon
atom. Both diamond and graphite are crystalline structures, but their crystals come in different
shapes.
