Graphite is made of carbon atoms arranged into extremely thin sheets (they are many atoms wide, but only one atom thick.) The sheets are held together by very weak forces, so when you write, you exert enough force to pull the sheets apart, leaving some on the paper.

What makes diamond most suitable for cutting hard material while graphite best for making pencils?
Both diamond and graphite are alltropes of carbon. But the crystal structure of diamond makes it the hardest natural mineral, while the crystal structure of graphite makes it a natural for pencils.
What is the graphite of a pencil?
It is the part of the pencil that makes the mark on the paper. Pencils used to use lead for this but the lead has been replaced with graphite.

What element is present in lead graphite?
Graphite is a form of Carbon, so its carbon in lead graphite. Notice that lead itself is a different element but the term "lead graphite" is generally used for that black substance which makes the "lead pencils". Note that there is no lead in lead pencils, its carbon, in the shape of graphite.
What property of graphite makes it suitable for use as electrodes?
The electrical conductivity
What makes pencils write?
it's obviouly lead Actually, it isn't lead. Scientists said it was lead, and it circled around the world. Scientists then found out it was graphite, but it was too late. In pencils, there is a slim hollow 'tube'. In that tube, there is some graphite, (Yes, graphite, not lead. People mistook it for lead.) that is stuck into the tube and makes a pencil. When you sharpen it, the pencil sharpener is a certain shape that burns the graphite and covering in a certain way that sharpens the pencil.
What makes graphite?
Graphite is an excellent conductor of electricity and heat. Graphite can withstand extremely high temperatures and is not affected by majority of reagents and acids. This property gives graphite uses which are unique and peculiar.

Why graphite is used as lubricant?
According to Experts, graphite is used as a lubricant because it is dry lubricant and a solid material with a greasy feel which makes for a good source for applications where oil cannot be used. Graphite is used inside pencils. It slips easily off the pencil onto the paper and leaves a black mark. Graphite is also a component of many lubricants.
