Many people call it lead but it is actually graphite.
A pencil is a mixture because it does not chemically bond, which needs to happen for it to be a compound. An element is something that is pure so a pencil cannot be an element.

The grey or black core of a pencil is made of graphite which is a form (known as an allotrope) of the element carbon. To vary the hardness of the 'lead' in the pencil the graphite may be mixed with clay or some other substances.
The black stuff in the middle of the pencil is a mixture of graphite (an element that is mined) and clay.

Water is a compound. A pure metal is an element. Graphite (a pencil lead) is the element carbon. These are all examples of a pure substance.
The lead of a pencil is made mostly of the nonmetal carbon but the rest of the pencil is neither metal nor nonmetal (except for the bit of metal near the eraser) because it is not an element.
You're thinking of carbon. Both pencil lead and diamonds are allotropes of carbon.
Well there is Carbon, Hydrogen, and Oxygen which makes up the plastic outside of a pencil sharpener. To know what element can be found inside you would have to know what a pencil sharpener is made up of on the inside.
