Usually, electrical conductors have loosely bound electrons. Most metals are excellent electric conductors. The element that is the best electrical conductor is silver. Liquids that contain ions also conduct electricity. These include salt solutions, acids, and bases. 1. Silver 2. Copper 3. Gold 4. Aluminum foil 5. Graphite 6. Steel 7. Bronze 8. Br...
Most organic materials are electric insulators because electrons aren’t as free to move in covalent bonds. Sea water contains ions and conducts electricity, but pure water is an electric insulator. Some elements are either conductors or insulators, depending on their form or allotrope. For example, carbon is either a conductor or an insulator. Grap...
Most metals conduct heatas well as electricity. But, electrical and thermal conductivity don’t always go hand-in-hand. For example, diamond is an electric insulator, but an excellent thermal conductor. Crystalline materials often conduct heat. 1. Silver 2. Gold 3. Copper 4. Diamond 5. Stainless steel 6. Aluminum 7.

Thermal insulators resist the flow of heat. Building and clothing materials are often insulators. Although you might expect glass to be a thermal conductor, it’s actually an insulator. Thermal insulators either contain open space in their structure or else their atoms and molecules are irregularly arranged. 1. Water 2. Polystyrene foam 3. Plastic 4...

ISBN: 978-81-224-1536-0.In science, a conductor is a material that permits a flow of energy. A material that allows the flow of charged particles is an electrical conductor. A material that enables the transfer of thermal energy is a thermal conductor or heat conductor.
Negatively charged ions are called anions. Simply, an electrolyte is a substance that can conduct an electric current when melted or dissolved in water. Electrolysis is the process of passing an electric current through a substance in the molten or aqueous state thereby decomposing it.

5 days ago · Conductors are defined as the materials or substances that allow electricity to flow through them. Also, conductors allow heat to be transmitted through them. Examples of conductors are metals, the human body, Earth and animals. The human body is a strong conductor.
What are conductors and insulators? Solids can be classified as conductors, insulators, and semiconductors. The flow of charge is defined as the electric current, and those materials that readily allow the flow of charge through them are termed as conductors.
A conductor is a material which contains movable electric charges. In metallic conductors, such as copper or aluminum, the movable charged particles are electrons, though in other cases they can be ions or other positively charged species.
