A diamond and a pencil lead (graphite) are both made of carbon. The difference is the crystalline structure of the carbon atoms.
Both diamonds and pencil lead are made out of the element carbon. The difference lies in their structures: diamonds have a crystal lattice structure, while pencil lead is made up of layers of graphite.
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.
