Why do some substances conduct?

When an ionic compound dissolves in solution, the ions of the molecule dissociate. These ions are electrochemically charged in solution and can conduct electricity, making them electrolytes. 3) Metals conduct electricity because the delocalized bonding allows the electrons to move from one place to another.

Why do some elements conduct electricity better than others?

So, why do certain metals conduct larger currents than others? Some metals contain more free electrons per cubic metre than others. In general the more free electrons the better the metal will conduct (for a certain applied voltage) although this is not always the case.

Which of the following materials is not considered to be a conductor?

Metals are generally very good conductors, meaning they let current flow easily. Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators. You will notice this if you have ever plugged something into a wall outlet.

Why do all materials not act as conductors?

All materials do not act as conductors because of absence of free electrons. In most of the cases these charged particles are electrons. Metallic substances have free electrons and hence they act as conductors.

Why do you think some objects conduct heat and electricity?

Metals contain free moving delocalized electrons. When electric voltage is applied, an electric field within the metal triggers the movement of the electrons, making them shift from one end to another end of the conductor. Electrons will move toward the positive side. Metal is a good conduction of heat.

Why do some metals conduct better than others?

why do metals conduct heat and why are some metals better than others at conducting heat? Most ordinary metals have about the same density of electrons (number per volume), so the main reason for the differences in how well they conduct electricity is the difference in how easily the electrons move around.

How is a conductor different from an insulator?

How is a conductor different from an insulator? In a conductor, electric current can flow freely; in an insulator, it cannot flow freely.

Can non metals conduct electricity?

Graphite is a non-metal and it is the only non-metal that can conduct electricity. You can find non-metals on the right side of the periodic table and graphite is the only non-metal that is a good conductor of electricity.
