Most transition metals are good conductors of electricity, copper one of the cheapest and best conductors. Because of its high density, electrons can flow from molecule to molecule without expending excessive energy. Copper is used in many things for conducting electricity. For example, in electric motors, copper wire is spun around a metal core to create electricity with the spinning of it within a magnet.
Such substances are called conductors.Generally, metals are good conductors of both heat and electricity.
Metals - metallic elements -are good conductors of heat and electricity.
Examples are gold, silver, copper (the copper group).
Metals are good in both.
Yes, this is mostly true. It starts to become untrue near silicon.
Upon melting, the ions are free to move and conduct electricity.
Aluminum is a conductor, and a pretty good one. It acts to conduct quite well. It ranks behind silver, copper and gold. Use the link to a list of things by their electrical conductivity. That link is below, and it is to Wikipedia, of course.Aluminium is a conductor.
Yes, aqueous sodium chloride solution is a good conductor of electricity. Since, it is an ionic salt, when dissolved in water it dissociates into ions and thus the free ions conduct electricity.
It's a good conductor of current flowing in one direction, and a good insulator when current tries to flow in the other direction.
Yes, this is mostly true. It starts to become untrue near silicon.
Air is a good conductor of sound, and a poor conductor of heat and electric current.

Tab water is a conductor of electric current but not a good one due to low degree of ionization of water. But if it has significant amount of salts then it will be a good conductor.
a metal
It is a semi conductor
Aluminium is a light weight metal having atomic number 13 placed in the 3rd period and having 3 valence electrons. It is a good conductor of heat and electric current and it does not corrode.
no it is good conductor because it has free electrons
