Your question: Which substance is a good conductor of electricity when solid?

The structures of graphite and diamond are shown below. Most network solids are non-conductors, although graphite is an exception and is a good conductor of electricity. The solid structure in graphite involves large, two-dimensional molecules of covalently bonded carbon atoms.

Which substances can conduct electricity when solid?

There are two types of substances that are good conductors or electricity. Metals conduct in the solid phase because they contain electrons that are mobile, or free to move around. When a copper wire is used in an electrical circuit it has electrons moving through it whenever the switch is closed.

Is solid a good conductor of electricity?

A solid is soft, good conductor of electricity and has very high melting point. Its one of the allotropic forms is the hardest known substance.

What solid is the best conductor of electricity?

The best conductor of electricity is pure silver, but to no surprise, it is not one of the most commonly used metals to conduct electricity. … The second drawback is the most obvious—it is simply too expensive to run silver wire through a building—far more expensive than aluminum or copper.

Can a solid substance conduct electricity?

Ionic solids do not conduct electricity; however, they do conduct when molten or dissolved because their ions are free to move. Many simple compounds formed by the reaction of a metallic element with a nonmetallic element are ionic.

GOOD TO KNOW:  Quick Answer: Is it legal to ride an electric scooter on the pavement?

What are 5 good conductors?

Conductors:

  • silver.
  • copper.
  • gold.
  • aluminum.
  • iron.
  • steel.
  • brass.
  • bronze.

What makes a good conductor of electricity?

For a material to be a good conductor, the electricity passed through it must be able to move the electrons; the more free electrons in a metal, the greater its conductivity.

Which metal is the best conductor of heat?

Metals That Conduct Heat the Best

  • Silver. Silver is one of the best metals for conducting heat because it works as a powerful reflector. …
  • Copper. Copper is yet another good conductor of heat because it absorbs heat quickly and holds it for a long period of time. …
  • Aluminum. …
  • Brass.

Is gold the best conductor of electricity?

Gold is used as a contact metal in the electronics industry as it is a good conductor of both electricity and heat. … Gold wire Gold is ductile: it can be drawn out into the thinnest wire.
