What are conductors in science?
Conductors are materials that permit electrons to flow freely from particle to particle. An object made of a conducting material will permit charge to be transferred across the entire surface of the object.
What is electronic conductor?
In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge (electrical current) in one or more directions. Materials made of metal are common electrical conductors.

What is harder than diamond?
Buckypaper. It is well-known since the late 20th-century that there’s a form of carbon that’s even harder than diamonds: carbon nanotubes. By binding carbon together into a hexagonal shape, it can hold a rigid cylindrical-shaped structure more stably than any other structure known to humankind.
Can electricity pass through a diamond?
The crystal structure has no free electrons that can flow or travel between potential differences. Hence, no electricity (or little electricity) passes through diamond crystals which makes them poor conductors of electricity.
Why does diamond not conduct electricity but is very strong?
Diamond is a giant covalent structure; each valence electron (outer shell electron) of every carbon atom forms a covalent bond, which means that there are no free electrons. Since electrical conductivity relies on the flow of free electrons, diamond is not a good conductor.
Why Graphite is a good conductor of electricity and diamond is not?
Graphite can conduct electricity because of the delocalised (free) electrons in its structure. These arise because each carbon atom is only bonded to 3 other carbon atoms. However, in diamond, all 4 outer electrons on each carbon atom are used in covalent bonding, so there are no delocalised electrons.
What is the hardest mineral prove?
Diamond
What is the hardest natural substance in the world?
diamonds
Can I crack a diamond?
Diamonds do not crack. You will either chip the diamond completely or not all.
Will a diamond shatter if heated?
A real diamond wouldn’t be affected by the drastic temperature change and simply sink to the bottom of the glass, but a fake diamond would shatter immediately.
