Why does buckminster fullerene conduct electricity?
Because, like graphite, it has got delocalized electrons. These electrons, when the C60 is exposed to a potential difference, are free to move towards the positive pole of the potential difference. But it's not the better conductor compared to graphite. Graphite has more weaker forces on its layers. This makes it more lubricant and therefore more electrically conductive.

Thanks for the feedback!
Yes, each carbon forms 3 covalent bonds leaving free electrons that can conduct electricity!
I think it can be explained by the fact that when you put salt into water, salt molecules NaCl divide themselves into ions : Na+ and Cl- . As they carry an electrical charge, …they are put in motion by the electrical field created by the generator (a battery for example), thus a current can flow in salted water and it is said that salted water conducts electricity. It's a bit the same thing in metals for electrons, which carry a negative charge. Sugar molecules do not divide themselves into ions when they are put into water, they remain neutral, so they cannot participate to conduction. Sugar is a molecular compound which in most cases cannot conduct electricity underwater. The salt is ionic so it can conduct electricity underwater.(Kind of like a summary)
First, it depends on the specific gasoline blend, the amount of ethanol blended into it, and the temperature of the fuel. In general the following values are used for electr…ical conductivity: Gasoline: 1x10-14 mho/cm (without any ethanol blended in is ) Ethanol (95% purity): 10-9 mho/cm For reference the electrical conductivity of Diesel fuel is 1x10-12 mho/cm. In the United States ethanol is currently blended with gasoline at up to 10 volume percent. Relevant units: mho= 1/ohm (reciprical ohms) S= Siemen 1 S = 1 mho
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.
Electrical conductance is the reciprocal of electrical resistance. From Ohm's law the resistance is defined as the ratio of the potential difference to the current produced by… it in the conductor.resistance =potential difference /current.conductance = current / potential difference. Conductance of a material gives an idea of how easily it will conduct current. Silver has more conductance than aluminum or iron. Silver will have more current than aluminum or iron when connected to the same electric cell.
The discovery The serendipitous discovery took place during experiments involving a cluster beam which uses a laser to vaporise a graphite rod in a helium atmosph…ere to produce carbon plasmas. The research was aimed at characterizing unidentified interstellar matter. Mass spectrometry evidence from these experiments indicated that carbon molecules with C60 atoms were forming, with a spheroidal geometry being most likely. In 1989 work by Krätschmer, Fostiropoulos and Huffman later produced C60 by arcing carbon rods in an inert atmosphere. Production efficiencies were claimed to me much higher then those produced using the cluster beam. Their finding were confirmed by IR and UV measurements The structure was named after the architect Richard Buckminster Fuller's geodesic dome structure which bore a resemblance to the structure of the C60 Buckminsterfullerene structure. These same structures are also known as Buckyballs or fullerenes. Buckminsterfullerene is the third allotrope of carbon along with graphite and diamond. Since their discovery, Buckyballs have become such a hot topic of research that they have spawned their own branch of chemistry. So much so that the journal "Fullerene Science and Technology" dedicated to fullerenes was launched in 1993.
We know that in, general, metals and superconductors, as well as plasmas and ionic solutions conduct electricity. Of the metals, silver conducts electricity the best, althou…gh it is relatively expensive. Copper is very commonly used because it is the second most conductive metal. We know that Group 1 and Group 2 metals (the alkali and alkaline earth metals) from the periodic table are good conductors. Other metals and metal alloys will also conduct, such as gold, aluminum, tungsten, brass, lead, bronze, iron ferrite, meteorite, tin, steel, iron, titanium, etc. Aluminum is also often used because it is highly conductive, and it much lighter than the other highly conductive metals. At very low temperatures (meaning the temperature of liquid nitrogen), superconductors are by far the best conductors available. These are far superior to any known metal, but, they do not conduct at anything close to room temperature. Some superconductors have zero resistance, and so there are absolutely no current or power losses as electrons move through the material. The general idea is that any material with free electrons will be a conductor. The more free electrons, the better the conductor will be. We also know that ionic solutions will conduct electricity. Salt water is an example of this. It should be noted that these materials include those in the solid, liquid and gas phases. As a plasma (an ionized material), electrons are suddenly made available to support conduction because of the fact that electrons have been torn from their orbits to ionize the material in the plasma. There will be a few more minor inclusions, and you can find more information by using the links.
Fullerenes are prepared by vaporizing graphite rod in helium atmosphere. A mixture of fullerenes like C 60 , C 70 etc are formed which are separated by solvent extraction met…hod.C 60 is obtained by column chromatography using alumina as the adsorbent and hexane as the solvent.
Yes It Does.
From my understanding, I would say that a solution need electrons movement to conduct electricity.
All metals, and also graphite, can conduct electricity.
Insulators. Their valence electrons are tightly bound because the valence shell is close to full or full. Since each shell can only only hold a certain amount of electrons, th…e number of electrons depends on which shell is the outer or valence shell.
Endohedral fullerene - Introducing and trapping of atoms inside the spherical carbon cage. Addition reactions This 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
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.
Commercial uses of fullerenes Although fullerenes are not yet used commercially, applications are being researched, such as catalytic methane activation to higher hydrocar…bons funded by the US Dept of Energy. Other properties of fullerenes and their compounds such as superconductivity have yet to be exploited.
