Want this question answered?
Metals are good conductors. Some non-metals are good conductors, but many others are not.
They generally look metallic but are brittle (not malleable or ductile). Neither good conductors or insulators but they are semiconductors.
The electrons in a metal can leave the atom and move about in the metal as free electrons. While atoms in non-metals are bonded. Heat energy is passed along by vibartions as the bonds between the non-metals atoms are shaken. Conduction in metals is faster than in non-metals. Making metals good conductors and making non-metals poor conductors.
Generally, non metals are non conductors (with exceptions such as graphite, fullerene etc)
Metalloids are known as semi-conductors meaning they can conduct electricity, but they are not good conductors. Metals are good conductors. Non-metals are bad conductors.

metals are good conductors of heat, i.e. iron, steel,... non-metals are bad, i.e. carbon...
Mainly metals. All metals are fairly good conductors. Some non-metals can conduct electricity, as well.
No, they are not good conductors of electricity. Graphite is an exception as despite being a non-metal it conducts electricity. Only metals are good conductors of heat as well as electricity.
Non metals :P

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.
Some nonmetallic materials are good conductors, graphite being an example. In this form, it is considered a semi-metal for that reason. Normally, however, nonmetals are not good electrical conductors.
