Pencil "lead" is not really lead, the metal - Pb. Pencils are made with graphite which is a mineral, an insulator.
Pencil "lead" is not lead metal. It is a mix of graphite and clay- nonmetal
It is mainly carbon in the form of graphite.
non metal
Non- metal
Metal
Lead is a soft ductile metal.
No. A pure diamond is carbon, and it is an allotrope of this element in the same way that graphite (pencil lead) is an allotrope of carbon. Thus, diamond is not a metal because carbon is not a metal.
Argon is known to be non-metal. This forms in a group of 13 or more.
Graphite itself is pure carbon. But it might be possible for some samples of graphite to contain impurities of lead.
Another answer on answers.com claims, "It's a common misconception that pencil lead is or has ever been constituted of the element lead. It's true that thousands of years ago the element lead was formed into cylinders and used to make marks on papyrus, however, wooden pencils or any instrument since does not use lead (lead is a heavy metal and using pure lead in form can cause major health problems with extended exposure). Pencils now are made of graphite or some other pigment. However, graphite in solid form was discovered in the 16th century and at the time was thought to be some type of lead, which is why many people today still call pencil lead: lead."This seems to be the most plausible explanation.
