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.
It is called a lead pencil. Despite the name, the "lead" in pencils is actually made of graphite, not lead. Lead pens are typically mechanical pencils that use a lead refill.
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.
No, pencil lead (graphite) is not magnetic because it does not contain any magnetic properties. Pencil lead is made of graphite, which is a form of carbon and is not attracted to magnets.
Pencil lead isn't really lead, it is graphite, a form of carbon. Pencil lead doesn't have any lead in it whatsoever.
No, a pencil is not poisonous. However, ingesting pencil lead or graphite can lead to an intestinal blockage or irritation.

Yes, pencil "lead" is not actually lead metal but graphite, which is a form of carbon. So, pencil lead is Pb (lead) free.
If the pencil contains graphite lead, it is not toxic and cannot give you lead poisoning. However, if the pencil contains actual lead or other harmful substances, it could pose a risk of lead poisoning if ingested or inhaled in large amounts.
Pencil lead is a compound
The 2 is the number of the lead in the pencil.
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.
