This document is about carbon and its different forms. It discusses how carbon exists in different allotropes, which are forms of the same element with the same chemical properties but different physical properties. The main crystalline allotropes of carbon are diamond and graphite. Diamond is hard, pure, non-conducting and transparent, while graphite is soft, conducting and non-transparent. Non-crystalline allotropes of carbon include coke, wood charcoal, animal charcoal and sugar charcoal. Carbon is able to exist in different forms due to the phenomenon of allotropy.
