As pencil is slippery in touch and the graphite is also slippery in touch. Also pencil is black in color as graphite is.

People beleive that mankind in stone age used agraphite stone to write on mud so scientist even tried to do same so pencils were created.

Graphite is very soft to easy sharp and very easy write on paper and its smothly removable.

GRAPHITE is black colour and it is soft and sharp. It is one of carbon. So pencil writes black.

Of couse graphite is used in making pencil leads but you know that graphite is a soft non metal and gets powdered easily in hand. So in order to make it hard its mixed with a substance. I don't exactly know the substance's name. If any one knows it please post it here as graphite is lustrous so to be used!
Graphite structure is hexagonal and it is build in layer which can slip in surface so it is used for pencil.

Its a non metal but good conductor of electricity and it is made of triple bond and three dimensonal.

Aside from being the material in your lead pencils, graphite is of tremendous value as an industrial material. It is used to make the brushes for electric motors and generators, and it has wide use as an electrode in a number of applications, primarily batteries.
Graphite has been, is, and will continue to be critically important to maintaining and advancing modern civilization. And this because it is in things we use every day, and because it is used in industrial processes that provide the foundation we build our society on.

Its a derivative of diamond and used in pencil and very soft.

Its a carbon compound and the graphite is very soft that's why it will easily broken.

The central lead of pencil is made of graphite which is black, soft and hence makes markable impressions on the paper.

As we all know carbon is a black element and the graphite is the softest allotropes of carbon. If you try. To break a pencil you will find the middle black part (graphite).
Easily breaks it makes impression on light surface it imparts carbon to the surface of paper therefore graphite is used in pencil.

Graphite is the allotropes of carbon. It is black and soft.
