On the atomic level, conduction occurs when electrons from individual atoms leave their valence shells to join a shared conduction shell, or band. This conduction band is the main region of electron flow involved in conduction. Metals are known to have a relatively small gap between their conduction and valence bands, meaning that less excitational energy is needed to bump an electron into conduction. This is a characteristic of an electrical conductor. Nonmetals have larger conductivity gaps, requiring more energy. This makes them insulators, and resistant to electron flow.
Metal is a good conductor because it has a high density of free electrons that can flow easily and carry electrical charge. Insulators, on the other hand, have a high resistance to the flow of electrons, preventing them from conducting electricity. Metal's properties make it a good conductor, while insulators have properties that make them poor conductors.
Metals are generally not good insulators because the highly mobile "sea" of loosely bound electrons makes them electrically and thermally conductive.
No. Most metals are good conductors of electricity and are not insulators.

Is magnesium a insulator?
yes
Why is radium a good conductor?
Radium is not a good conductor. In fact, radium is a poor conductor of electricity due to its low thermal and electrical conductivity. Its chemical properties make it an insulator rather than a conductor of electricity.
Is uranium a conductor or insulator?
Uranium is a metal and, therefore, a conductor of electricity.
Is a metal spring a conductor or insulator?
Most metal springs (steel, aluminum, etc) are conductors.
Is copper white a conductor or insulator?
Copper is a metal, so it has metallic bonding. This means that the electrons are free to move & carry a current. So copper is a good conductor of heat & electricity.
Is a fork a conductir or insulator?
If it is made of metal, it is a conductor. If it is wooden, it is an insulator.
Is a metal saucepan a good insulator?
Yes. Metal is a good conductor of heat.
Is iron a insulator?
No because it is a good conductor of heat and electricity!
Is a staple a conductor or insulator?
A staple is typically made of metal, which is a good conductor of electricity. Therefore, a staple is considered a conductor.
Is lead conductor semi conductor or insulator?
Lead is a metal and is considered a good conductor of electricity. It is not a semiconductor or insulator.
Is glass or metal a better conductor?
Glass has a higher conductivity than thin plastic but,it is still lower than metal so metal may be a better conductor
Is a nail a conductor of electricity or a insulator of electricity?
Anything made out of metal is likely to be a good conductor.
Is metal Doorknob a conductor or insulator?
conductor
Is magnesium a insulator?
yes
Is cotton a insulator or a conductor?
It is a insulator since it is not metal
Is fur conductor or insulator?
It is an Insulator because it is not a metal
Is platinum a insulator?
Platinum is a horrible insulator. Being metal, it conducts heat and electricity quite well.
