Conductors and Non-Conductors

Front

What is a conductor?

Back

A material allowing the flow of electric charge or a solid-state electrical conductor which conducts due to the movement of ions.

Front

Name some excellent conductors.

Back

Silver, Copper, Gold, Aluminum, Zinc, Nickel, Brass.

Front

What is a non-conductor?

Back

A material that does not transmit electrical currents, heat, or sound, or transmits it poorly.

Front

Name some poor electrical conductors.

Back

Rubber, Glass, Plastic, Dry Wood, Diamond, Air.

Front

What is an electrolyte?

Back

A compound that conducts an electric current when it is in an aqueous solution or melted.

Front

What must a substance contain to conduct a current?

Back

Mobile ions that can move from one electrode to the other.

Front

Are all ionic compounds electrolytes?

Back

Yes, all ionic compounds are electrolytes.

Front

What is a nonelectrolyte?

Back

A compound that does not conduct an electric current in either aqueous solution or in the molten state.

Front

Give examples of nonelectrolytes.

Back

Many molecular compounds, such as sugar or ethanol, are nonelectrolytes.

Front

What happens when nonelectrolytes dissolve in water?

Back

They do not produce ions.
