Lead was used for writing in Roman times. The 'lead' in a pencil is a mixture of graphite and clay. It is called lead because when the graphite deposit was first discovered in Borrowdale, England, the locals thought it was lead (or plumbago). Chemists later corrected them but the name has stuck.
Graphite is a form of carbon, like diamond, but softer.
Unlike lead, graphite is non-toxic.
lead pen because a lead pencil is a regular pencil.
The tip of a pencil is called the nib.
The point of a pencil is called the "lead" or "graphite tip."
The tip of a pencil is called the "lead" or the "point." It is the part of the pencil that is used for writing or drawing.
The pointed end of a pencil where the graphite or lead is located is called the pencil tip or pencil point.

Not to be picky, but I think you mean pencil. No, the Romans did not invent the lead pencil. In fact the "lead" in a pencil is not even lead at all. It is a material called graphite.
The pointed end of a pencil where the graphite or lead is located is called the pencil tip or pencil point.
A typical lead pencil does not actually contain lead. The "lead" in a pencil is made of graphite, which is a crystalline form of carbon. Therefore, there is 0% lead in a lead pencil.
The wood part of a pencil is called the barrel or casing. It holds the graphite or lead core in place.
There is no lead in pencil - Pencil is made from graphite
The part of the pencil that does the actual writing, called the pencil lead, is actually made of a mineral called graphite.
The number of the pencil is based on the type of carbon lead used inside. The thicker the carbon lead gets the higher the number of the pencil becomes. If you notice a mechanical pencil is 0.9mm in diameter so it would be called a #0.9 pencil. A #2 pencil's lead is 2mm in diameter. So Why would we call a pencil a #3 pencil? Because it's lead is 3mm in diameter.
A lead of a pencil is a conductor because it is made of graphite, which allows electricity to flow through it. Graphite is a good conductor of electricity due to the free movement of electrons in its molecular structure.
