diamonds form a 3 dimensional lattice. they also have have four bonds per atom. This makes a very strong material.
graphite forms a 2 dimensional lattice. it has 3 bonds per atoms (the fourth bond is added to the other three making partial double bonds). it forms sheets. it has excellent 2-d strength: it is what is used in carbon fibers. it also is an excellent lubricant because the sheets slide on one another.
fullerenes are like graphite, but the small sheets are wrapped up into small balls or tubes. this gives them 3 d strength on a nano scale. But they lack large scale 3d properties.

Is fullerene brittle?
Fullerene, a form of carbon composed of molecules shaped like hollow spheres, ellipsoids, or tubes, exhibits some brittleness under certain conditions. While it has a unique molecular structure that confers strength, it can become brittle when subjected to stress or strain, particularly in larger aggregates. In general, its mechanical properties can vary based on the specific type of fullerene and the environmental conditions. Thus, while fullerene can be strong, it can also show brittleness under specific circumstances.
What is larger fullerene?
A fullerene is a form of Carbon molecule that is neither diamond nor graphite. Fullerene molecules consist of 60 or more Carbon atoms, the smallest fullerene has no less than 60 carbon atoms (C60) and is called Buckminsterfullerene. Fullerenes are geodesic in shape (spherical like a football- hence the nickname buckyball) and are invariably closed at both ends.
How many bonds does carbon form in a fullerene?
Carbon forms three bonds in a fullerene structure. Each carbon atom in a fullerene is bonded to three other carbon atoms, forming a network of interconnected hexagonal and pentagonal rings.
A form of pure carbon with atoms arranged in the shape of a hollow sphere?
The form of pure carbon with atoms arranged in the shape of a hollow sphere is called a fullerene. Fullerenes, also known as buckyballs, were first discovered in 1985 and have unique properties that make them of interest for various applications, such as in nanotechnology and drug delivery systems.
How many carbon atoms are in the fullerene unit cell?
The fullerene unit cell typically contains 60 carbon atoms, corresponding to the most common form of fullerene known as C60. This structure resembles a soccer ball, composed of hexagons and pentagons arranged in a spherical shape. Depending on the specific type of fullerene, the number of carbon atoms can vary, but C60 is the most recognized and studied.
What causes graphite diamonds and fullerene to have different properties?
because they are of allotropes of carbon.

What is a endohedral fullerene?
Endohedral fullerene - Introducing and trapping of atoms inside the spherical carbon cage. Addition reactionsThis simple topology consideration alone makes it evident that the reactivity of the fullerenes is significantly different from that of classical planar 'aromatics". Addition and redox reactions lead to covalent exohedral adducts and salts, respectively. Subsequent transformations of specifically activated adducts pave the way to other classes of fullerene derivatives. These are heterofullerenes, defined degradation products or partial structures, open cage species and endohedral fullerenes, and exohedral fullerenes. Alternatively, some of the prototypes of fullerene derivatives can be obtained directly during the fullerene formation out of graphite in the presence of foreign elements, by particle implantation methods. Most of the endohedral metallofullerenes are currently generated during the fullerene formation whereas partial structures are basically provided from total synthesis. For all the prototypes of fullerene derivatives in some cases a large number, of examples have already been realized. Among the salts the superconductors M3C60 (M is, for example, an alkali metal are the most prominent representatives

What are the disadvantages of fullerene?
Some disadvantages of fullerene include their high cost of production, potential toxicity if not properly handled or modified, and limited solubility in common solvents. Additionally, there may be challenges in controlling their formation and purity during synthesis processes.
How many carbon atoms are in the fullerene unit cell?
The fullerene unit cell typically contains 60 carbon atoms, corresponding to the most common form of fullerene known as C60.

Depending on the specific type of fullerene, the number of carbon atoms can vary, but C60 is the most recognized and studied.
Is fullerene polar non polar or ionic?
Fullerene is a nonpolar molecule because it consists of only carbon atoms bonded together in a symmetrical shape. As a result, the distribution of electrons is uniform and there is no separation of charges within the molecule, making it nonpolar.
What is the thermal conductivity of fullerene?
The thermal conductivity of fullerene, specifically C60, is relatively low compared to metals, typically ranging from about 0.1 to 0.2 W/m·K at room temperature. This low thermal conductivity is attributed to its molecular structure and the weak van der Waals interactions between fullerene molecules. However, variations in thermal conductivity can occur depending on the fullerene form, purity, and temperature.
