first of all we need to know what is insulator and what is conductor, insulator is a substance in which there is no free electrons in the conduction band ,electrons in conduction band are responsible for a substance to be conductor.
now as there in diamond all the atoms are closley packed and are bounded by carbon carbon bonding there fore due to this there is no free electron and hence diamond is an insulator.

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.

∙ 14y agoDiamond is a good conductor because of the strong covalent bonds between the atoms, it results in a very rigid lattice structure. Also the purer the diamond the better. In quantum mechanics they think in terms of traveling phonons, the more rigid the lattice structure the faster the phonons travel. Also the lightness of the carbon atom results in a greater speed for the phonons. You can think of the photons as waves of vibration which travel at the "speed of sound" for the material. Also the more perfect the crystal the further the phonons travel before dispersing.
The thermal conductivity of diamond, which is four times that of copper, goes against the trend that most electrical conductors are better conductors of heat than insulators. This is usually the case because the free electrons of metals end up transporting the energy.

Will Teflon conduct electricity?
Teflon is an electrical insulator (not a conductor).
Why copper electrical wires need to be wrapped in plastic?
as plastic is a good insulator of electricity.
Which element is the best electrical insulator?
An insultor is somebody who insults. Elements don't tend to do that.
Is porcelain a conductors?
In general, porcelain is not a conductor. It is considered an insulator. It is possible to make ceramics that will conduct, but the porcelain we normally find is a good insulator.
Which metal acts as an insulator?
Metals are conductors, not insulators. Both electrical and thermal conductors.
Does diamond demonstrate electrical conductivity?
No. Diamond is a thermal conductor, but an electrical insulator.
What does an insulator do to electrical current?
It stops the flow of the electrical current.
Why diamond electrical insulators?
diamond is an electrical insulator since all valence electrons are fully involved in single (sigma)bond formation.thus no free electrons are available.
Which would be the best insulator carbon or silicon or aluminum or oxygen?
Oxygen. Carbon as diamond is a good electrical insulator, (graphite is an electrical conductor), silicon is a semiconductor so has limited electrical conductivity and aluminium is a metal and a good electrical conductor.
Is a glass microscope slide an electrical insulator or a conductor?
Yes, a glass microscope slide is an electrical insulator. Glass is generally considered an electrical insulator.
Is dimand a conductor or a insulator?
Diamond is an insulator.
Diamond is an insulator while graphite conducts electricity?
Diamond is considered the hardest mineral known to man, while graphite is one of the softest. Diamond is an excellent electrical insulator, while graphite is a good conductor of electricity. This is due to the way the carbon atoms are arranged in each mineral.
Are diamonds a good conductor of electrical energy?
Diamond is, in general, a poor conductor of electrical energy. Generally, we find that diamond is actually a pretty good electrical insulator. This contrasts sharply with its ability to conduct thermal energy, which it does better than anything else we know of.
Why is a diamond an insulator?
A diamond is an insulator because it has a full valence band and a large band gap between the valence and conduction bands. This means that it does not have any free electrons available for electrical conduction. Additionally, the carbon atoms in diamond are tightly bonded to each other through covalent bonds, making it difficult for electrons to move freely within the crystal structure.
An example of a insulator?
An insulator has several different meanings. The two most common are an electrical insulator and a thermal insulator. an electrical insulator would be polyethylene. a thermal insulator would be wool.
Give an example of an electrical insulator and an electrical conductor in the house?
conductor-copper insulator-rubber
Is plasticine a conductor or insulator?
Plastic is an electrical and thermal insulator.
