Detailed explanation-1: -Diamond and graphite are allotropes of carbon. Reason: Some elements can have different structural forms called allotropes.
Detailed explanation-2: -Graphite and diamond are two of the most interesting minerals. They are identical chemically – both are composed of carbon (C), but physically, they are very different. Minerals which have the same chemistry but different crystal structures are called polymorphs.
Detailed explanation-3: -Both diamond and graphite are made entirely out of carbon, as is the more recently discovered buckminsterfullerene (a discrete soccer-ball-shaped molecule containing carbon 60 atoms). The way the carbon atoms are arranged in space, however, is different for the three materials, making them allotropes of carbon.
Detailed explanation-4: -Diamonds, graphite and charcoal are all forms of carbon. Carbon is an element that has 12 protons.
