# What are diamond and graphite?

May 23, 2018

These are $\text{allotropes of carbon...}$

#### Explanation:

These are both carbon allotropes...of remarkably different appearance. Graphite is non-molecular in two dimensions...

The graphite layers can move with respect to each other, and thus graphite can act as a LUBRICANT....

...whereas diamond is non-molecular in THREE dimensions.

The strength of the carbon-carbon bonds in diamond makes diamond-tipped cutting tools very effective....
