The core of a pencil (used to be actual poisonous lead, now is made of graphite) is soft enough that it can deposit a layer of material when subject to friction (AKA "scratched").
The 'lead' or graphite in a pencil is softer. Try writing on paper, the pencil will write, the real lead will not
Graphite is the mineral that is used to make the lead in a pencil. Despite its name, pencil "lead" is actually composed of graphite mixed with clay.
Pencil lead is made of a mixture of graphite and clay, which wears out as you write due to friction between the lead and the paper. The abrasion caused by writing causes the graphite particles to break off, resulting in the lead becoming shorter and duller over time.

Compressed colored lead sticks can be used in mechanical pencils that are designed to accommodate them. Simply insert the lead stick into the pencil, making sure it is securely in place, and then use the pencil as you normally would to write or draw. Make sure to advance the lead as needed using the pencil's mechanism.
the mechanical pencil will write better because it has a skinnier lead, so the pencil doesn't go flat if you write too much on one side. the lead also still graphite, but has special substances in it to help you write better. Still, if your pencil is certified HB#2, it can be used on Scantron Genuine Forms and State tests.
Your pencil lead may be breaking because you are applying too much pressure while writing or drawing. Try using a lighter touch to prevent the lead from breaking. Additionally, make sure your pencil is sharp and not worn down, as a dull tip can also cause lead breakage.
pencil lead is not charcoal but rather graphite molded with clay and hardened
A "pencil lead" is a mixture of the graphite allotrope of carbon mixed with clay and baked hard. While a pencil lead will conduct electricity, it can not be used to make a light bulb.

Graphite is the mineral that is used to make pencil lead. It is a form of carbon that is known for its ability to make marks on paper.
