Why can sodium chloride conduct electricity in the …

In order to conduct electricity a substance must have charge particles, such as electrons and ions, that are free to move freely through it. In the solid state, ionic compounds such as sodium chloride have their ions fixed in position and therefore these ions cannot move so solid ionic compounds cannot conduct electricity. However in the molten

They either have an extended three-dimensional covalent network-lattice structure, as exemplified by diamond (carbon) and silicon dioxide (sand), SiO 2, and silicon, Si. Or they present as discrete molecules like fluorine, F 2 , methane, CH 4 , or glucose, C 6 H 12 O 6 that interact with each other via weak (van der Waals/dipole-dipole/hydrogen bonding) forces.

Electrical and Thermal Conductivity of Diamond

26/8/2018· Most diamonds are extremely efficient thermal conductors, but electrical insulators. Diamond conducts heat well as a result of the strong covalent bonds between carbon atoms in a diamond crystal. The thermal conductivity of natural diamond is around 22 W/ (cm·K), which makes the diamond five times better at conducting heat than copper.

Why does graphite conduct electricity

Graphite is not as good a conductor as copper, but it is relatively cheap and thus, more and more products are being used which utilize the unique conduction properties of graphite. With more consumer products utilizing graphite, more expensive metals like copper and gold can be phased out, which means the end consumer saves money, since graphite conducts electricity just as well as copper or

Can silicon conduct electricity? - Answers

24/9/2010· Why graphite conducts electricity but silicon carbide does not? Because graphite has one free electron that is not involved in bonding. The one delocalized electron can be used to conduct electricity.

Why does graphite conduct electricity? - BBC Science …

19/12/2020· Answer: the very reason why metals do. “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.
