Metals have fewer electrons in their valence shell ( outer most shell ) which allows the electrons to move freely throughout their structure. Metals also tend to be reactive and have a low melting point, which allows them to easily transfer heat/electricity!
( For a more detailed answer research the "band theory" of metals )
All do - some just have greater conductivity than others
yes
Yes.
yes
Not in its solid state. It will conduct electricity if molten or dissolved in water.
the majoriy of metals are good conductors such as cooper and iron other metals such as gold are not
Not in their standard solid states, but they can if molten or dissolved in water.
They are silvery metals that conduct electricity.
All metals can conduct sound, but some conduct it a bit better than others.
Mainly metals. All metals are fairly good conductors. Some non-metals can conduct electricity, as well.
yes all materials conduct electicity , but some are good conductor , some poor and some very poor
All metals conduct electricity.All metals conduct electricity.All metals conduct electricity.All metals conduct electricity.
