What substances would you expect to conduct electricity?
Metals conduct electricity in the solid state because the valence electrons of the atoms generate a mobile “sea” of electrons. Water is a good solvent for many covalent and ionic compounds. Substances that dissolve in water to form electrically conducting solutions are electrolytes.
Which substances would most likely conduct electricity?
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.
Which of the following substances is an electrical conductor?
Some common conductors are copper, aluminum, gold, and silver. Some common insulators are glass, air, plastic, rubber, and wood.
Which of the following substances would be a good electrical conductor?
An electrical conductor is a substance in which electrical charge carriers, metals conduct electricity, the best is silver and copper.
What are three substances that can conduct electricity?
Yes, zinc chloride and potassium iodide. Some substances are ionic, but electrical conduction is only possible when the ions are free and mobile. This happens once the solid has been melted. Phenylsalicylate, polythene, wax and sugar are covalent.
What types of substances conduct electricity and why?
- Solid ionic compounds don’t conduct electricity. …
- Solutions of ionic compounds and molten ionic compounds can conduct electricity because the ions are free to move around. …
- Metals conduct electricity because the delocalized bonding allows the electrons to move from one place to another.
Which of the following is most likely to conduct electricity the fastest?
Silver has the highest electrical conductivity of all metals. In fact, silver defines conductivity – all other metals are compared against it. On a scale of 0 to 100, silver ranks 100, with copper at 97 and gold at 76.
Which of the following substance is of electricity?
Answer: Ionic substances, also known as salts, conduct electricity when dissolved in water or when in the liquid state (molten).
Which is the conductor?
An electrical conductor is a substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage. Copper, steel, gold, aluminum, and brass are also good conductors. …
Which of the following substance is not a good conductor of electricity?
Explanation: Germanium (symbol: Ge) is a chemical element, which is neither an insulator nor a good conductor of electricity.
