Why is diamond harder than graphite?
Understand the Problem
The question is asking about the difference in hardness between diamond and graphite, which involves understanding their molecular structures and bonding. This is a chemistry-related question that relates to the properties of carbon allotropes.
Answer
The carbon atoms in diamond are bonded in a stronger tetrahedron pattern.
Diamond is harder than graphite because the carbon atoms in diamond are bonded in a stronger tetrahedron pattern while graphite is arranged in layers with only weak Van der Waals forces holding the layers together.
Answer for screen readers
Diamond is harder than graphite because the carbon atoms in diamond are bonded in a stronger tetrahedron pattern while graphite is arranged in layers with only weak Van der Waals forces holding the layers together.
More Information
The carbon atoms in diamonds form a three-dimensional network of strong covalent bonds, making it extremely hard. In contrast, graphite consists of layers of carbon atoms bonded together with weaker forces, allowing the layers to slide over each other easily.
Tips
Remember to consider the types of bonds and structures when comparing properties of materials.
