The graphite in pencils is called "lead" due to a historical misunderstanding. In the 16th century, graphite was thought to be a form of lead ore. Despite its incorrect naming, the term "lead" has persisted in reference to pencil graphite.
When the graphite deposit that produced the first pencils was discovered, the people thought it was lead. Later, chemists told them it was graphite, a form of carbon, but the 'lead pencil' had already become so popular that the name persists to this day.
Graphite pencils typically have a matte finish, while lead pencils have a shiny appearance. Additionally, graphite pencils produce darker markings compared to lead pencils of the same grade.
Mechanical pencils, like the regular kind of pencils, use graphite.
Pencils are no longer made with lead. They are made with a mixture of graphite and clay. This combination produces the "lead" in modern pencils.
No. This is totally untrue. There is no lead in pencils - not even in the paint they are painted with! The reason for this is caused by confusion over the name of the filler. The substance inside a pencil that does the actual writing is called graphite. This is a crystalline form of carbon (another is diamond, another is a substance called buckminsterfullerene, and the third, non-crystalline form, is charcoal). The graphite is often mixed with differing amounts of clay to create pencils of different hardnesses. Graphite is found as a mineral in the ground. Lead is also found as a mineral in the ground as the lead ore 'lead sulphide' or 'Galena'. The mineral Galena looks very similar to graphite, except that graphite is darker in colour than lead ore. Therefore, many years ago graphite used to be called 'black lead' from its appearance. So, when pencils were invented, they were filled with graphite - or 'black lead', and eventually this was shortened to 'lead' but there is absolutely no connection with the 'lead' (i.e. black lead) found in pencils with the metal lead. The "lead" in pencils was always, is, and always will be, made of graphite.

pencils such as lead pencils
Graphite pencils typically have a matte finish, while lead pencils have a shiny appearance. Additionally, graphite pencils produce darker markings compared to lead pencils of the same grade.
Mechanical pencils, like the regular kind of pencils, use graphite.
both, lead is made of graphite.
Lead was never actually used in pencils. The "lead" in pencils is actually a mix of graphite and clay. The switch to using graphite in pencils occurred in the 16th century.
Pencils are no longer made with lead. They are made with a mixture of graphite and clay. This combination produces the "lead" in modern pencils.
graphite
Not in modern pencils. They contain graphite.

People around the world don't put lead in lead pencils or any pencils! They put something called graphite. They use graphite because lead is poisonous. If a peice of lead touched you, you would have poison in you. Then eventually you would die. So that is what people put in lead.
Pencils switched from using actual lead to graphite in the 16th century, when it was discovered that graphite was a more suitable material for writing due to its softer and darker marks than lead. This change occurred in England around 1564.
