Our common pencils have a writing core of a mixture of graphite and clay, enclosed in a (generally) wooden body. This body is made in two parts intended to be joined together. The outer shape may be round, hexagon, triangle etc, as wished. In the middle of each half is a groove to hold the lead snugly. Glue is used to hold the two halves together, and also the writing graphite core.
Only very seldom, and with rough treatment will the two halves of the body separate.
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.
In pencils, "F" stands for "fine." It indicates the hardness of the pencil lead, with an "F" pencil falling in the middle of the hardness scale between "HB" and "H." A "F" pencil produces lines that are somewhat fine and have a moderate level of darkness.
lead pen because a lead pencil is a regular pencil.
No. Also, "pencil lead" is not lead; it is almost always graphite (made of carbon)

There is no lead in pencil - Pencil is made from graphite
Pencil lead is a compound
If your asking if the pencil has Lead, then the answer is that most pencils do NOT have lead in them anymore.
Pencil lead isn't really lead, it is graphite, a form of carbon. Pencil lead doesn't have any lead in it whatsoever.
Pencil lead is a conductor.
we get lead of pencil from the mixture of clay and graphite
A 9mm pencil lead is thicker than a 7mm pencil lead.
Pencil lead is made of graphite and clay. Newer recipes for pencil lead use waxy polymers to bind the graphite to produce a lead that does not snap when the pencil is flexed.
