Why is graphite slippery?
ChemistryMaterials
Quick Answer
Graphite is slippery because its carbon atoms are arranged in layers that slide over each other easily. Weak forces between the layers make it act like a lubricant.
The Full Story
In graphite, each carbon atom bonds strongly to three others in a flat sheet, leaving electrons delocalized across the layer. The layers are held together only by weak forces, so they can move over one another with little resistance. This is why graphite feels greasy and is useful in pencils, lubricants, and some high-temperature applications. Its structure also explains why graphite conducts electricity along the layers.
Key Facts
1.Graphite has layered structure
2.Weak interlayer forces let layers slide
3.Graphite conducts electricity along the layers
