What is an allotrope? Provide an example and what allotropes are they of.

Atoms of the same element but with different structure. For example diamond and graphite, they are allotropes of carbon. (/≧▽≦)/

Why does graphite conduct electricity?

1 carbon atom is bonded to 3 others in graphite (carbon - 4 valence electrons), thus the delocalised electrons can move along the layers...(o゜▽゜)o☆
