Why does graphite conduct electricity even though it is a non-metal?
In the question we have that graphite is the only non-metal which can conduct electricity. In graphite each carbon is bonded to three other carbon atoms hence leaving behind a free electron. Due to the presence of this one delocalised electron, graphite is a good conductor of electricity.
Why does graphite conduct heat and electricity?
Graphite has delocalised electrons, just like metals. These electrons are free to move between the layers in graphite, so graphite can conduct electricity. The forces between the layers in graphite are weak. This means that the layers can slide over each other.
Why graphite is a good conductor of electricity but bad conductor of heat?
No, graphite is a conductor of electricity due to it’s structure where each atom is bonded with 3 other carbon atoms in sheets held together by weak van der waal’s force. The one electron of each carbon atom is free, which is responsible for conduction of electricity. But it is not a good conductor of heat.
Which of the following is a non-metal but still conduct electric current *?
Graphite
Graphite is a non-metal. But still it conducts electricity.
Which non-metal is good conductor of heat?
Name a non-metal which is good conductor of heat and electricity. Graphite is good conductor of heat and electricity.
Why does a pencil conduct electricity?
“Metals conduct electricity as they have free electrons that act as charge carriers. Graphite is just the same,” says Dr Dong Liu, physics lecturer at the University of Bristol. As she points out, graphite is made from carbon atoms, which have four electrons in their outer shells.
Is graphite a non metal?
Carbon is a solid non-metal element. Pure carbon can exist in very different forms. The most common two are diamond and graphite….Diamond and graphite.
| Diamond | Graphite |

| Hard | Soft |
Why graphite is a good conductor of?
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.
Why diamond is good conductor of heat?
Thermal conductivity Unlike most electrical insulators, diamond is a good conductor of heat because of the strong covalent bonding and low phonon scattering. Thermal conductivity of natural diamond was measured to be about 2200 W/(m·K), which is five times more than silver, the most thermally conductive metal.
How is graphite different from a diamond?
Graphite and diamond are two of the most interesting minerals. They are identical chemically – both are composed of carbon (C), but physically, they are very different. Graphite is very soft and has a hardness of 1 to 2 on this scale. Diamonds are the hardest known natural substance and have a hardness of 10.
