graphite, the substance that makes the lead of your pencil is mostly carbon in one form. It is very soft, which is what makes it work as pencil lead because as you run it across a piece of paper, the graphite rubs off onto the paper.
diamond is pure carbon in another form, and is the hardest naturally occurring substance known to man.

What are epimers?
Epimers are refer to one of two optical isomers that differ from each other only in the configuration about one asymmetric carbon atom (that is, the epimeric carbon).
What chemical weathering process occurs when minerals in the rock react to carbon dioxide?
Carbon dioxide plus water can dissolve minerals.
Can minerals be elements or compound?
They can be either. Gold and carbon are both elements that occur as minerals in element form. Carbon in fact takes two mineral forms: graphite and diamond. Most minerals are compounds. Some of the simpler ones include silicon dioxide (quartz), aluminum oxide (corundum), and sodium chloride (halite).
What minerals does the hope diamond have in it?
Carbon and boron.
Are Carbon Hydrogen Nitrogen and Oxygen minerals?
No they are not.
In what ways do minerals differ each other?
minerals differ in appearance and texture
What is in camera film?
a camera film contains carbon and hydrogen. two minerals
What is camera filming?
a camera film contains carbon and hydrogen. two minerals
How do different isotopes of an element differ?
Two isotopes differ in the number of neutrons in the nucleus. For example, Carbon-14 has 8 neutrons differing from Carbon-12 which has 6 neutrons.
What are minerals considered to be?
A mineral has a fixed chemical composition, and crystal format. Sometimes we may have two minerals with the same chemical formula - e.g. calcite and aragonite, but differ in crystallization.
True or false two isotopes of carbon are carbon-12 and carbon-14 theese isotopes differ from one another by two ELECTRONS?
False, different isotopes of the same element have different numbers of neutrons.
List two distinct ways in which minerals are differ from vitamins?
Vitamins are complex molecules, whereas minerals are singular elements. Vitamins are only required in minute quantities whereas some minerals are required in larger amounts.
How does the composition of most minerals differ from the pure element?
Minerals (other than elemental minerals) are combinations of elements.
What are minerals that form the diamond?
carbon
Which minerals are found in graphite?
Carbon
