Why are diamonds harder than graphite?
Understand the Problem
The question is asking about the difference in hardness between diamonds and graphite, which are both forms of carbon. This involves understanding their atomic structure and bonding. Diamonds have a strong covalent bonding structure, while graphite has a layered structure with weaker van der Waals forces between the layers.
Answer
Diamonds are harder than graphite due to diamond's strong tetrahedral structure compared to graphite's weakly bonded layers.
The final answer is that diamonds are harder than graphite because diamond has a strong tetrahedral structure while graphite consists of layers held together by weak Van der Waals forces.

More Information
Both diamond and graphite are allotropes of carbon, meaning they are forms of the same element but with different atomic arrangements, giving them distinct physical properties.
Tips
A common mistake is not recognizing that the difference in hardness is due to the arrangement and type of bonds between the carbon atoms.
