The fourth electron between the layers is delocalised. These particles can either be electrons or ions, and they’re responsible for carrying the electric charge through any substance. Science journals have been running out of superlatives for this wondrous stuff: it's just about the lightest, strongest, thinnest, best heat- and electricity- conducting material ever discovered. As we know carbon has four valence electrons, and one remaining electron of carbon is delocalized and move to free across the lattice to conduct electricity. The resistance also plays an important role in determining the type of conductor. Why is Graphite Slippery / Used as a lubricant. Can graphite conduct electricity? In a graphite molecule, one valence electron of each carbon atom remains free, Thus making graphite a good conductor of electricity. So guys, if you have any questions, you can leave a question in the comment section. Resistance is the measure of obstacle offered to the flow of electrons that conducts the electricity.eval(ez_write_tag([[580,400],'techiescientist_com-medrectangle-3','ezslot_2',103,'0','0'])); Resistance is usually generated by the heat caused when kernels collide to each other when electrons move fastly across it when voltage is applied across that element. Diamond does not conduct electricity, so how does graphite conduct electricity? That's why they conduct electricity; just depending on it's structure: graphite is pure uncrystallised pure carbon and conducts electricity, diamond is pure crystallized unconductive carbon The bond angle formed between the carbon atoms is 120 degrees. Graphite carries the properties of metal and non-metal as well that make it a unique element. The honeycomb layout of the stacked carbon atoms of graphite leaves a single electron unbound in each hexagon. Conductivity in Covalent Crystals: There are four categories of crystals: ionic, covalent, molecular, and metallic. In diamond the bonds are sp and the atoms form tetrahedra with each bound to four nearest neighbors. Fact Check: Is the COVID-19 Vaccine Safe? The µΩ/m is referred to as ohms per meter. Diamond and Graphite both are mineral of carbon having the same composition but with different chemical structures. Is graphite a good conductor of electricity? Graphite is used in the manufacturing of pencil lead since the 16th century. Graphite is a very good conductor of electricity because of the presence of the delocalized electron. Graphite is a good conductor whereas diamond is an insulator. The calculated resistivity of pure graphite is calculated as 1.38 * 10^-5 µΩ/m. the layers can easily slide over each other making graphite soft and slippery and an excellent lubricant (like oil). Each carbon atom forms a covalent bond with four other adjacent carbon atoms. The U.S. Supreme Court: Who Are the Nine Justices on the Bench Today. Yes, graphite is a very good conductor of electricity because of delocalized electrons. Each carbon atom is connected to its adjacent three carbon atoms. The specific gravity of this element is found around 2.1 to 2.3. Graphite and Diamond both are allotropes of Carbon, yet diamond is a bad electrical conductor and graphite is a good conductor of electricity. Comments (1) Report plz mark as brainliest Log in to add a comment Suhaniv Ambitious; Yes! Graphite can conduct electricity due to the vast electron delocalization (delocalized electrons are electrons in a molecule, ion or solid metal that are not associated with a single atom or one covalent bond) within the carbon layers (a phenomenon called aromaticity). That is the sp3 hybrid. Thanks 1. And the elements that do not have any delocalized electrons present to move are classified as insulators because there are no electrons present to flow current across it. This delocalization results in an equidistant bond length between all six bonds in each honeycomb cell of the graphite structure. And why doesn't diamond do the same? Yes, graphite is a very good conductor of electricity because of delocalized electrons. Graphite is an interesting material, an allotrope of carbon (as is diamond). If we talk about the lattice structure of diamond, carbon atoms form a three-dimensional network resulting in a tetrahedral structure. Graphite conducts electricity because it possesses delocalized electrons in its structure. Each carbon is bonded to 3 other carbons - This means that there is one electron that is not bonded - it is free to to move through the structure, carry current and conduct electricity.
