Some pencil's are filled with lead, but rarely any nowadays. Pencils use to be filled with lead, but now pencils are typically filled with graphite as lead is poisonous to humans.
A typical lead pencil does not actually contain lead. The "lead" in a pencil is made of graphite, which is a crystalline form of carbon. Therefore, there is 0% lead in a lead pencil.
A 9mm pencil lead is thicker than a 7mm pencil lead.
lead pen because a lead pencil is a regular pencil.
A mechanical pencil would likely float in water due to its lightweight and buoyant materials such as plastic and metal components. However, if the pencil is filled with enough heavy lead to outweigh its buoyancy, it may sink.

Pencil lead isn't really lead, it is graphite, a form of carbon. Pencil lead doesn't have any lead in it whatsoever.

The 2 is the number of the lead in the pencil.
Pencil lead is a compound
we get lead of pencil from the mixture of clay and graphite
Pencil lead is a conductor.
The formula for pencil lead is a combination of graphite mixed with clay. The most common type contains graphite and clay in a ratio of approximately 80:20. The clay acts as a binder to hold the graphite together and determine the hardness of the lead.
