Graphite also has a lower density (2.266 grams per cubic centimeter) than diamond. The planar structure of graphite allows electrons to move easily within the planes. This permits graphite to conduct electricity and heat as well as absorb light and, unlike diamond, appear black in color.
Why do diamond and graphite look different?
When you look at graphite and diamond, it is hard to imagine that they are identical chemically, for they are so different physically. Graphite is opaque and metallic- to earthy-looking, while diamonds are transparent and brilliant. Another important physical difference is their hardness.
How do graphite and diamond differ in their structure?
Diamond: each carbon atom bonds to 4 other carbon atoms, WHILST, Graphite: each carbon atom bonds to 3 other carbon atoms. Thus, diamond bears more of a tetrahedral structure, whereas graphite takes the form of layers. The presence of layers means that atoms can slide over each other easily.
How are diamonds and graphite the same How are they different quizlet?
How are diamonds and graphite the same? How are they different? Both diamonds and graphite are made entirely out of carbon. They are different because the carbon atoms are arranged differently with a more three-dimensional structure in diamonds and flat layers in graphite.
What are the similarities and differences between graphite and diamond?
Diamond and graphite are both allotropes of carbon. This means they are both made up of carbon atoms arranged differently and exist in the same physical state. They both have a giant covalent structure. Diamond has a tetrahedral structure and is the hardest material known to man.
Why is the graphite softer than the diamond even though it is made up of the same substance?
Graphite is a form of carbon in which the carbon atoms form covalent bonds with three other carbon atoms. … These layers can slide over each other, so graphite is much softer than diamond.
What is different in the structures of graphite and diamond quizlet?
In graphite, the bonds between atoms in different layers are very weak, and the layers slide past one another easily. … The difference between a diamond and graphite is a diamond is bonded with four and graphite is with three.
Do diamond and graphite have different arrangements of atoms?
Both diamond and graphite are made entirely out of carbon, as is the more recently discovered buckminsterfullerene (a discrete soccer-ball-shaped molecule containing carbon 60 atoms). The way the carbon atoms are arranged in space, however, is different for the three materials, making them allotropes of carbon.
How can you use differences in carbon bonds to explain why graphite and diamonds have different properties?
Graphite and Diamond are different because they have different structures. Both have Giant Covalent Structures, resulting in very high melting temperatures. However each carbon atom in Diamond has 4 covalent bonds with other Carbons, making it extremely strong and hard.
