: Diamond is made up of pure carbon. In the structure of diamond one carbon atom is attached to four other carbon atoms forming a covalent bond. All the electrons of each carbon atom is shared and the octet rule is satisfied. Hence no free electron is left for the conductance of electricity. : In case of graphite the carbon atoms naturally combine covalently with three other carbon atoms so every combined carbon has one unshared or free electron. Now this free electron is responsible for conductance in graphite. : Graphite and metals have free electrons to conduct electricity.
Graphite can conduct electricity because of the delocalised electrons in its structure. These arise because each carbon atom is only bonded to 3 other carbon atoms. Generally, in diamond, all the 4 outer electrons on each carbon atom are used in covalent bonding, so there are no other delocalised electrons.
Graphite conducts electricity because it has delocalized electrons that are free to move and carry an electric current. In contrast, diamond does not conduct electricity because it has a fully bonded and rigid three-dimensional lattice structure, which does not allow for the movement of electrons.
This is how I understand it: It has to do with the structure of graphite & diamond. Graphite has a layered structure of carbon atoms, one on top of another (kind of like sheets of paper stacked together). To form this structure the carbon atoms have three of its 4 outer electrons bonded with 3 other carbon atoms. The unbonded 4th electrons move freely between the graphite layers. This is why it is able to conduct electricity. The structure of the diamond has all four of its outer electrons bonded to 4 other carbon atoms, so there are no free electrons & thus it is a non-conductor of electricity. Hope this explanation helps.
In the bonding of graphite, the carbon atoms bond to form layers of hexagonal rings. and in each ring, there is one delocalised electron that allows electricity to be conducted. In diamond, the carbon atoms bond to form a tetrahedral, rigid arrangement. This does not allow electricity to be conducted as the electrons in the bonds are not free to move.
Like a metal, graphite is a very good conductor of electricity due to the mobility of the electrons in its outer valence shells. Other allotropes of carbon (like diamond) do not have the same electron mobility, and are not as conductive.

Does carbon conduct electricity?
No, carbon in its pure form is not a good conductor of electricity. However, certain forms of carbon like graphene and carbon nanotubes can conduct electricity due to their unique structure and properties.
Does magnetite conduct electricity?
Rock is generally an insulator. Note that the color of a rock is usually not a good indicator of is composition of properties.
Is carbon an insulator or a conductor?
Carbon can be either an insulator or a conductor, depending on its form. In its pure form as graphite, carbon is a good conductor of electricity due to its delocalized electrons. However, in other forms like diamond, carbon is an insulator because its electrons are bound tightly within the atoms.
Explain why graphite conduct electricity but silicon carbide does not?
Graphite can conduct electricity due to the presence of delocalized electrons in its structure, allowing for the flow of electrical charge. Silicon carbide, on the other hand, is a covalent compound with a polarized ionic structure that lacks free-moving electrons, making it a poor conductor of electricity.
Why is graphite a conductor of electricity but is a non metal?
Graphite is a conductor of electricity due to its structure, which allows electrons to move freely between layers. While graphite has a non-metallic elemental composition (carbon), its unique layered structure allows it to conduct electricity like a metal.
Why do carbons not conduct electricity?
Graphite and diamond are good electricity conductors.
Do diamonds conduct electricity?
they don't conduct electricity: they have no free electrons. graphite, however, made of the same stuff as diamond (carbon) has a different structure, which means that it does have free electrons, and a lot of them. Therefore graphite is a good conductor of electricity.
Why blue diamond can conduct electricity?
Blue diamonds can conduct electricity because they contain trace elements of boron, which can act as an impurity or charge carrier in the diamond's crystal lattice. This allows for the movement of electrons and the flow of electricity within the diamond structure.
Which non metal conducts electricity?
Graphite, which is a form of carbon, is a non-metal that can conduct electricity due to its unique structure that allows electrons to move freely through its layers.
Diamond is an insulator while graphite conducts electricity?
Diamond and graphite are both forms of carbon, but their different structures result in different electrical properties. Diamond has a tightly bound crystal lattice that does not allow the movement of electrons, making it an insulator. In contrast, graphite has a layered structure with delocalized electrons that can move freely between layers, allowing it to conduct electricity.
Does carbon conduct electricity?
No, carbon in its pure form is not a good conductor of electricity. However, certain forms of carbon like graphene and carbon nanotubes can conduct electricity due to their unique structure and properties.
Is the lead of a pencil (graphite) can conduct electricity.?
Yes.
Does Graphite conduct electricity in all directions?
yes
What property makes graphite an unusual non metal?
Graphite is an unusual non-metal because it has a layered structure with weak forces between the layers, allowing them to slide over each other. This gives graphite its lubricating properties and ability to conduct electricity along the planes of its structure.
Why graphite is good conductor of electricity while diamond is not?
Graphite is a good conductor of electricity beacause graphite is sp-2 hybirdize orbit
Will a line drawn by a pencil conduct electricity?
Yes, pencil lines can conduct electricity to a certain extent, as the graphite in pencils is a form of carbon which can conduct electricity. However, it may not be as effective a conductor as other materials designed specifically for that purpose.
Does wodden causing from a pencil conduct electricity?
No, wood is an insulator and does not conduct electricity. The graphite in the pencil lead, however, is a conductor of electricity.
