Graphite is one of the allotropes of carbon a) Define the term allotropy
b) Identify the other allotrope of carbon
c) State two uses of graphite ​

When an element exists in more than one crystalline form, those forms are called allotropes; the two most common allotropes of carbon are diamond and graphite. Every carbon atom is covalently bonded at the four corners of the tetrahedron to four other carbon atoms.
