Why does graphite conduct electricity but diamond doesn t?
Why is diamond not a good conductor of electricity? As we know diamond is a giant covalent structure i.e. each carbon atom is covalently bonded with other carbon atoms. So the four outermost electrons, four carbon atoms, are engaged or trapped in the covalent bonds which means that there are no free electrons. So diamond is a bad …Web

Why is graphite a good conductor of electricity but not diamond?
Diamond on the other hand consists of a 3D lattice structure with each carbon atom bonded to four other carbon atoms in a tetrahedral shape. This structure is extremely strong, but it keeps electrons in place, which is why diamond cannot conduct an electrical current. Answer link. The carbon atoms are bonded differently in each substance.Web

Why graphite is a conductor but not a diamond?
Graphite is a conductor but not diamond because: In graphite, each carbon atom is linked to three carbon atoms via a C - C covalent bond. The fourth electron is delocalized so it is mobile and can conduct electricity. But diamonds have no free electrons because each carbon is four other carbon atoms covalently bonded in a tetrahedral manner.Web

Does Graphite Conduct Electricity? (Yes. But Why?)
Graphite conducts electricity. It has free electrons that conduct electricity by carrying charge from one location to another. Each carbon atom in graphite has a covalent link with three other atoms, freeing one atom. The free electron moves across the graphite material and does not bond to any particular atom. Free atoms can leave that layer or move to one …Web

How electricity is generated
Most U.S. and world electricity generation is from electric power plants that use a turbine to drive electricity generators. In a turbine generator, a moving fluid—water, steam, combustion gases, or air—pushes a series of blades mounted on a rotor shaft. The force of the fluid on the blades spins (rotates) the rotor shaft of a generator.Web

Does Carbon Conduct Electricity: 11 Facts You Should Know
Carbon conducts electricity due to the loosely bounded electrons in the outermost shells. The band gap is said to be large in carbon so the conduction of electricity or heat is low. The energy gap for carbon is 5.4ev and when the size decreases the band gap increases so conduction is merely possible.Web
