Coal, graphite and diamonds are all allotropes of carbon and are stable at room temperature.
Graphite is a form of Carbon, so its carbon in lead graphite. Notice that lead itself is a different element but the term "lead graphite" is generally used for that black substance which makes the "lead pencils". Note that there is no lead in lead pencils, its carbon, in the shape of graphite.
Graphite is a naturally occurring mineral like coal.
Diamonds, coke, coal, graphite, fullerenes
Well to be very upfront diamond is very heated and compressed carbon (coal graphite) while graphite is more "pure" carbon than diamonds

Graphite is used to make pencil lead, but it is not a form of coal.

Graphite is a pure form of coal or carbon. It is a good conductor of heat and electrcity. It is used as a neutron moderator in nuclear reactors of type Gas Cooled reactors.

Diamond, coal, graphite, coke and buckminsterfullerene are composed primarily of carbon and are insoluble in water.
Yes. Other allotropes include coal and graphite, such as you might find in a pencil as 'lead'.
That would be coal. --------------------------------- The correct answer is Carbon - Coal is also a form of carbon as is Graphite. There are 3 grades of Coal - Lignite, which is 55% Carbon - Bituminous, which is 75 to 90 percent Carbon and Anthracite,which is 90% Carbon and 10% impurites.(such as Sulfur) In summary- Diamond, Coal and Graphite are all Different forms of Carbon

Graphite.
Like diamonds, graphite is what's known as an allotrope of carbon. That means it is actually carbon, although it ocurs in a different form in nature. Graphite occurs naturally as an ore; it is considered by some to be a high form of coal, although this reference is uncommon as graphite is hard to light and makes a poor fuel source.
