Explanation: The layers of graphite’s structure are held together by van der Waal forces. Graphite is incredibly silky and slippery because it cleans readily between the layers. As a result, it is used in pencils and as lubricants in high-temperature equipment.
Key Points:
- Graphite is a crystalline form of carbon with a hexagonal arrangement of atoms
- Under normal conditions, graphite is the most stable form of carbon
- nder extreme pressures and temperatures, it transforms into diamond
- Graphite is a mineral that is found in lubricants and pencils
