Name the crystalline forms of carbon.

Carbon shows allotropy. The various allotropic forms of carbon can be broadly classified into 2 classes a) Crystalline form b) Amphorous form Diamond and Graphite are the 2 crystalline forms of carbon. In diamond, the carbon atoms are arranged tetrahedrally while in graphite, the carbon atoms are arranged inregular hexagons in flat parallel layers In (CO_(3)^(2-)) , carbon atoms shows

It is converted into

_______, ________ and _____ are the three crystalline forms of carbon.

_______ and _______ are the two crystalline forms of carbon.

_________ is a soft crystalline form of carbon.

PASSAGE-I : Diamond and graphite are two allotropic forms of carbon which are crystalline in nature. They differ physically but chemically they are similar. Diamond is the hardest crystalline form of carbon. In diamond each carbon atom is linked to four other carbon atoms by covalent bonds. In graphite, each carbon atom is linked to three other carbon atoms by covalent bond. Graphite is relatively soft and greasy. It is a good conductor or electricity. Which allotrope gives carbon dioxide on heating?
