Graphite is used to make lead for the pencils.

An element may exist in more than one physical form. These different physical forms of an element are called its allotropes.

• Graphite is an allotrope of carbon.
• Graphite is used to make lead for the pencils because graphite is a form of carbon that is soft and creates an impression on the paper

Hence it is used as a pencil lead.
