Graphite

Graphite is a form of carbon with a distinct layered structure. It is a non-metal and is one of the three naturally occurring allotropes of carbon, the other two being diamond and amorphous carbon.

Here are some key points to remember about graphite:

1. Structure: Graphite consists of layers of carbon atoms arranged in a hexagonal lattice. The layers are held together by weak van der Waals forces, which allows the layers to slide over each other easily.
2. Properties: Graphite is a good conductor of electricity due to the delocalized electrons in its structure. It is also a lubricant because of the slippery nature of its layers.
3. Uses: Graphite is used in pencils, lubricants, electrodes in batteries, and as a material for heat-resistant products.
4. Formation: Graphite forms under high temperature and pressure conditions, often in metamorphic rocks.
