Anything foreign under the skin is not good, however his body will push it out eventually. Graphite is not really a poison per say, and children that ingest pencil graphite (chewing on it) have no ill effects.
Summary
Besides having a little mark if it's shallow enough to see, no he is fine.

No. It is a physical change, because the graphite is still graphite.
more graphite and less clay
Lead is poisonous so eating lead would be harmful. However most pencils are now made from graphite, although people refer to it a lead still. Graphite from a pencil is harmless.
The number two in reference to a pencil denotes the relative hardness of the graphite or "lead" that is in the pencil, HB being softer and three being harder, etc.
: Pencil "Lead" Is made out of Graphite and graphite is NOT flammable. However some brands of "lead" have a coating that is. If you expose a pice of "lead" to an open flame the coating will quickly burn away, the flame will extinguish, and the "lead" will remain. (still useable)
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.
First off, its spelled "breaking". No, Its a physical change, because the pencil hasn't changed its chemical components, all you did was ruin a pencil. :)
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.
Not as far as I know. You would have to find a very old pencil. These days a pencil's inner core is mostly made of a form of carbon usually known as graphite. Suke girl.
No. Graphite is not poisonous, not even in the form that is inserted into pencils. Graphite is occasionally ingested to absorb poisons before vomiting is induced. Still, it is not exactly recommended to chew on your pencil graphite 24/7. It won't kill you, though.
Lead and graphite are two entirely different materials.Lead is a heavy and dense metal; it is soft, malleable, and melts at a low temperature. It is also toxic.Graphite occurs naturally and is a form of crystalline carbon.Though people often refer to a lead pencil, the lead in the pencil is in fact graphite.
Lead has never been used in lead pencils. The lead in a lead pencil is made of graphite, a form of carbon, together with clay and other additives that hold it together. Owing to a poor understanding of science, the graphite deposit that produced the first pencils was originally thought to be lead. The term is still used to refer to the core of pencils.
