Properties of carbon
1) It is a non metal having high melting point (3800C) and high boiling point (4300C).
2) Allotropy: Carbon has several allotropes, or different forms in which it exists. The hardest naturally occurring substance (diamond) and one of the softest known substances (graphite) and another allotrope is fullerene.
3) Catenation property: Carbon has the ability to form very long chains of strong and stable interconnecting C-C bonds. This property allows carbon to form an almost infinite number of compounds
