silicon, which is a semiconductor.
Air is a relatively-very-poor electrical conductor. If it were any good as a conductor,then you would need to keep your spare batteries in vacuum containers, to preventtheir becoming discharged through the air between their terminals.
A good conductor is a substance that will easily carry loose ions, also known as electricity. Many metals are good conductors. Conductors have many modern applications. Any wire that carries an electrical current has to be a conductor of some sort. On the contrary, substances that do not conduct electricity are known as insulators. Rubber is a very common insulator.
Silver is a good thermal conductor as it's a metallic element with many free electrons available for heat transfer.
metal is a good conductor :)
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.
a metal
Upon melting, the ions are free to move and conduct electricity.

aluminum, copper,
Tranition metals
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
