What makes graphite a good conductor of electricity?
In a graphite molecule, one valence electron of each carbon atom remains free. Due to the free electrons in its framework, graphite can perform electricity. Therefore, graphite is said to be a good conductor of electricity.
What makes graphite soft and good conductor of electricity?
Graphite is soft lubricant and good conductor of electricity as it has pi bonds. The pi bonds of graphites are are one over another so it is soft lublicant and as it has pi bond so it can conduct electricity.
Why is graphite a poor conductor of electricity at high temperatures?
Graphite is an allotrope of carbon. It has the properties of bot metals and non-metals. At higher temperature, graphite has an intermolecular structure with immobile ions. Thus, this makes graphite a poor conductor.
Why is graphite slippery and conducts electricity?
The delocalised electrons are free to move through the structure, so graphite can conduct electricity. The layers in graphite can slide over each other because the forces between them are weak. This makes graphite slippery, so it is useful as a lubricant .
Why is graphite is good conductor of electricity but diamond is non conductor of electricity?
In a graphite molecule, one valence electron of each carbon atom remains free, Therefore graphite gained a name of a good conductor of electricity. Whereas in diamond, they have no free mobile electron. so it has been said that diamonds are bad conductor electricity.
What allows graphite to conduct electricity?
Graphite is able to conduct electricity, due to delocalization of the pi bond electrons above and below the planes of the carbon atoms. These electrons are free to move, so are able to conduct electricity. However, the electricity is only conducted along the plane of the layers.
Is graphite a heat conductor or insulator?
Graphite is a good conductor of heat for the same reason it is a good conductor of electricity. Electrical Conductivity of Graphite is due to loose electrons,which are results of De-localized bonding in the layers. (This is the cause for anisotropy in Graphite). Is Diamond an insulator?
Why is graphene a good electrical conductor?
The reason graphite is a good conductor of electricity is because of the presence of delocalised electrons, as each carbon atom forms only three covalent bonds with three other carbon atoms. The delocalised electrons are free to move throughout the graphite layers under the influence of an applied electric field 🙂
Which element is good conductor of electricity?
In general, metals like copper and aluminum are the best conductors of electricity. Good conductors are able to allow electrons to easily flow through.
