Carbon. Diamond is the crystalline form, while graphite (pencil "lead") is the powdered form.
graphite in a pencil and diamond are from carbon .both are the allotrope of carbon
Carbon. Diamond and graphite (pencil lead) are allotropes of carbon, meaning different atomic arrangements of the same element. They are also both covalent network solids.
A diamond and a pencil lead (graphite) are both made of carbon. The difference is the crystalline structure of the carbon atoms.
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.
Many people call it lead but it is actually graphite.
Pencil lead is actually not lead (Pb) at all, but it is graphite. And graphite is simply carbons atoms. So, no, it is NOT a compound mixture.
NO! Lead is a chemical element itself, with no particular relation to carbon, which is another chemical element. The common allotropes of carbon are diamond and graphite. -------- Lead is the common name for the substance in a 'lead' pencil which does indeed contain an allotrope of carbon known as graphite.
Pencil 'lead' does not contain crystals. It is a mixture of the element carbon (in the form of graphite) and clay.
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.
Water is a compound. A pure metal is an element. Graphite (a pencil lead) is the element carbon. These are all examples of a pure substance.
