The Atomic Difference Between Diamonds and Graphite ...

Diamond (left) and graphite (right) are both made of carbon atoms, but arranged in different ways. Image source. In graphite, all the carbon atoms have strong chemical bonds to three other carbon atoms, making sheets that look like chicken wire; weak forces hold the sheets together in stacks that can slide past each other easily.
