A pencil mark primarily consists of graphite, which is made up of carbon atoms. In a typical pencil mark, there are approximately 10^19 to 10^20 carbon atoms in a single mark, depending on its size and thickness. This vast number reflects the microscopic scale of atoms and the relatively small quantity of graphite used in a pencil mark.
Graphite, which is a complex molecule of carbon atoms.
Graphite is present in pencil leads. it is composed of carbon atoms covalently bonded with each other, and 1 free valence electron in each atom (which explains why graphite/pencil-lead conducts electricity)
A diamond and a pencil lead (graphite) are both made of carbon. The difference is the crystalline structure of the carbon atoms.
The graphite core of a wooden pencil is the best conductor of electricity because graphite is made up of carbon atoms arranged in layers that allow for the easy flow of electrons. The wood casing of the pencil acts as an insulator and does not conduct electricity.

Carbon constitutes pencil lead, charcoal and diamond. Although they appear different in appearance, they are chemically the same. Diamond is shiny and hard due to the crystalline arrangement of carbon atoms in it. Graphite or pencil lead has such an arrangement, that there are free electrons which make it a conductor of electricity. Elements like this, which are chemically the same but exhibit different physical properties are called allotropes, and the phenomenon is termed as allotropy.
Pencils are made by graphite. It is a form of carbon. Graphite has sp2 hybridized carbon atoms.
A pencil is made of carbon atoms bonded together in a crystalline structure. These atoms form graphite, which gives the pencil its characteristic dark color and allows it to leave marks on paper when writing.

Metallic bonds are typically found in the graphite core of a pencil, which is what allows the graphite to conduct electricity. Graphite is a form of carbon that consists of layers of atoms held together by metallic bonds.

Though the archetypal pencil was an artist's brush, the stylus, a thin metal stick used for scratching in papyrus or wax tablets, was used extensively by the Romans,[3] and for palm-leaf manuscripts.
Pencil "lead" is actually made of graphite, which is an inorganic mineral. Graphite is made up of carbon atoms and is not considered organic.
Graphite. You might have come across experiments using a pencil to complete a simple circuit to check if a bulb glows and you might have observed that it does. The graphite in the lead of the pencil is what helps conduct electricity.
