Not in modern pencils. They contain graphite.
Led can be found in Led pencils and some other things as well
No, we don't use galena is pencils. Galena is the primary ore of the metal lead, and this mineral, PbS, is recovered for that purpose. We also often recover silver as a byproduct of lead processing. It is graphite that is used in pencils, and the mineral graphite is an allotrope of carbon.

The "lead" found in pencils is actually graphite, or to answer the question, the "blackelement found in a pencil is carbon (C).
pencils such as lead pencils
The lead in pencils are not made out of lead, as is common belief. Pencil lead is made out 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 contain lead. lead is dangerous for humans. many students put pencils in there mouth and can lead to lead poisoning. This can bring lawsuits against companies for negligence as the companies know the pencils contain lead which is toxic.
Lead is mainly used for pencils and for batteries.Hope this helped :)

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.
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.
