Um. I think its because its black and black conducts heat. DON'T TELL YOUR TEACHERS THIS IT'S JUST AN IDEA! Please if you do tell them that its an idea and if you'r old enough to go to uni or collage you should be answering this, not me.
"things that conduct electricity" is a very common question, but however is different than "what things conduct electricity" things like water with salt dissolved into it, wood, metal, and SOME plastics conduct electricity, but copper and silver are the best even though people think gold is.
Some materials that conduct electricity include metals like copper, silver, and gold, as well as carbon in the form of graphite. In addition, solutions containing ions, like saltwater, can also conduct electricity.
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.
When graphite was first discovered it was thought to be a kind of black lead, rather than a form of carbon. It was quickly found to easily make marks, but brittle and needed support. The wooden lead pencil was born
Some weird conductors include human skin, graphite (pencil lead), and even fruit such as lemons and potatoes. These materials can conduct electricity to varying degrees, but they are not commonly used in electrical circuits due to their unpredictability and inefficiency.
Graphite is the only non-metal exception that can conduct electricity. Hence, even though graphite is a non-metal, it is used in batteries.
graphite is a form of carbon that forms in layers which is why it is able to be used in pencils, because the layers can slide off and get left on the page. Anyway carbon is a non-metal so graphite is a non-metal.
The missing words in that sentence are "left" and "hydrogen".

Taste it. Try to conduct electricity. Evaporate a sample.
Graphite is less dense than diamond, due to the differences in crystal structure.
Bromine is not a metal. It is a nonmetal halogen and is the inly nonmetal that is liquid at room temperature. Its chemical symbol is Br and has an atomic number of 35. It is reddish-brown in color with a metallic luster (even though it is not a metal).
Some materials that conduct electricity include metals like copper, silver, and gold, as well as carbon in the form of graphite. In addition, solutions containing ions, like saltwater, can also conduct electricity.
Metals like copper, aluminum, and gold are good conductors of electricity. Other materials like graphite, seawater, and certain types of acids can also conduct electricity. Conductivity depends on the ability of materials to allow the flow of electric current.
Nitrogen is not considered to conduct electricity. This gas lacks the free electrons to support conduction.

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.
