What do graphite and diamond have in common?
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.
What is the difference between diamond graphite and fullerenes?
Diamond, graphite and fullerene are allotropes of carbon. The key difference between diamond graphite and fullerene is that diamond has a diamond cubic crystal structure and graphite has a hexagonal crystal structure, while fullerene occurs as a large spheroidal molecule.
What is the relation between diamond and graphite?
Diamond and also graphite are chemically the same, both made up of the element carbon, however, they have entirely different atomic and also crystal frameworks. Diamond atoms have a rigid 3 dimensional structure with each atom carefully loaded with each other as well as connected to 4 other carbon atoms.
Why does diamond and graphite have similar properties?
Explanation: Diamonds and graphite are both allotropes of Carbon. Allotropes are compounds of the same composition, but exists in two or more different forms due to the different bonding. … It’s because the carbon atoms are rearranged in a specific geometric shape that gives the diamond its properties.
What type of structure do diamond and graphite have?
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.
What do diamonds buckyballs nanotubes and graphite have in common?
Diamond, graphite and buckyballs are examples of the variety of ways carbon atoms can join together, and are particularly interesting because they contain only carbon atoms.
What property does graphite have in common with most metals?
Graphite has delocalised electrons, just like metals. These electrons are free to move between the layers in graphite, so graphite can conduct electricity. This makes graphite useful for electrodes in batteries and for electrolysis.
What two key properties do fullerenes have?
Their unique molecular structure results in extraordinary macroscopic properties, including high tensile strength, high electrical conductivity, high ductility, high heat conductivity, and relative chemical inactivity (as it is cylindrical and “planar” — that is, it has no “exposed” atoms that can be easily displaced).
What are 3 differences between diamond and graphite?
Difference between diamond and graphite.
The p-Block Elements.

What are the properties of a diamond?
Besides the hardness, diamond provides an impressive combination of chemical, physical and mechanical properties:
- Low coefficient of friction.
- High thermal conductivity.
- High electrical resistivity.
- Low thermal expansion coefficient.
- High strength.
- Broad optical transparency from ultra violet to infra red.
What is fullerene structure?
Fullerenes are molecules composed entirely of carbon with spherical (buckyballs), ellipsoid, tubular (nanotubes) or a combination shape (nanobuds). They consist of hexagonal and pentagonal (sometimes also heptagonal) rings, with the latter necessary for the curvature of the molecule.
Do diamond and graphite have the same properties?
Since they are both made of carbon their chemical properties are the same. Most physical properties of a solid like hardness, melting point, conductivity of heat/electricity, etc. largely depend on it’s crystal structure. Graphite and diamond have very different structures.
How do diamond and graphite differ in their properties?
For example, Graphite and diamond are two different allotropes of carbon.
Explain the difference in properties of diamond and graphite on the basis of their structures.
