carbon exist naturally in the pure state as wood in impure combine state as coal as amorphous such as diamond and graphite

alade6440; There is a mistake graphite and diamond is not amorphous but crystalline cos they have solid shape.

jhuedalo; typographic error,diamond and graphite are allotropic form of carbon giving diamond octahedral shape, graphite as hexahedral and other lacks shape and that is the reason they are referred as amorphous

As a various form.. They are two forms of allotrope which are crystal and non crystal.. Diamond and graphite are classified as crystalline carbon.. While coal, charcoal, soot are classified as non crystalline allotrope of carbon.
