using the energy band model, i would rank metals as good conductors. The energy gap in metals is negligible, that is the valence band and the conduction band overlap. Thus it is very easy for electrons in the valence band to move to the conduction band thereby conducting currents. Hence metals are good conductors.

Which materials are good or bad conductors of heat?

metals are good conductors of heat, i.e. iron, steel,... non-metals are bad, i.e. carbon...


What are some good conductors and bad ones?

Good Electrical conductors: All metals, ionic substances (in solution or molten form) Bad Electrical conductors: Water Good Heat conductors: All Metals Bad Heat Conductors: Water


Are all types of metals good conductors?

No, not all metals are good conductors. Some metals, such as copper and aluminum, are excellent conductors of electricity and heat due to their large numbers of free electrons. Other metals, like lead and stainless steel, are poor conductors because their electrons are not as free to move.


What are the differences between good and bad conductors of heat?

Good conductors of heat, such as metals like copper and aluminum, have high thermal conductivity due to their free electrons that can easily transfer heat energy. Bad conductors, or insulators, like wood or rubber, have low thermal conductivity as they lack free electrons and impede the flow of heat energy. The molecular structure of good conductors allows for efficient heat transfer through collisions between free electrons and atoms, while bad conductors have a structure that inhibits the flow of heat energy.


What are good conductors called?

Good conductors are called materials that allow electric current to flow through them easily due to the mobility of their electrons. Some examples of good conductors include metals like copper, silver, and gold.
