Carbon. Diamond is the crystalline form, while graphite (pencil "lead") is the powdered form.
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.
A pencil is typically made of graphite, which is mixed with clay and other additives to create a writing core. The outer casing of a pencil is usually made from wood, but it can also be made from plastic or recycled materials.
No. Also, "pencil lead" is not lead; it is almost always graphite (made of carbon)
lead pen because a lead pencil is a regular pencil.
Pencil Tip is made of Lead, but nowadays it is usually made of Graphite.

A diamond and a pencil lead (graphite) are both made of carbon. The difference is the crystalline structure of the carbon atoms.
Lead is an element, it is not made of anything but lead. But if you are talking about pencil lead then pencil lead is made of graphite.
there both made up of carbon
there both made up of carbon
Yes, carbon.supplement. when an element exists in two or more forms, these forms are known as an allotrope. Carbon has three allotropes, graphite, diamond, and ordinary carbon.
there both made up of carbon
graphite in a pencil and diamond are from carbon .both are the allotrope of carbon
A sharpened pencil lead is non-metallic. It is typically made of graphite, which is a non-metallic element.
The grey or black core of a pencil is made of graphite which is a form (known as an allotrope) of the element carbon. To vary the hardness of the 'lead' in the pencil the graphite may be mixed with clay or some other substances.
