As graphite is a hard and non-metal, brittle also allotropes of carbon, and it is black and soft.

Graphite because it is allotropes of carbon, black and soft and NON-METAL and both have same features and slippery in nature so this way GRAPHITE is use for making pencil.

As graphite is a hard and non-metal, brittle also allotropes of carbon, and it is black and soft.

Graphite is a metal. It is black in colour and very smooth for use. So it is use in pencils.

Because graphite is carbon it has in black color it can easily wrote in paper.

graphite is a soft &sharp so it is use in pencil.

Graphite is used in pencil because it is softness, smoothness and removable.

Yes. Graphite is a form of carbon. It forms a network covalent solid, which causes layers of C atoms on top of each other. This allows the layers of carbon to slip over each other and gives pencils the ability to write. Hence graphite is used in pencils.

The graphite is an allotropic form of carbon that consists of atoms of carbon that possesses a kind of hybridization in a way that three strong bonds are forming a equilateral triangle in the same plane and a weaker bond perpendicular to that plane.

This allows that carbon arranged in parallel "sheets" that slide one each other giving the graphite a high lubricant performance.

That is the reason that is used in lead pencils: each graphite sheet slides on the paper surface when we write on it, leaving carbon atoms adhered on it. We saw the result as writing characters.

Early lead were used. Now Graphite is being used.
