Good conductors contain many free electrons.
F. Conductors!
Metals are generally good conductors because they have many free electrons that are able to efficiently transfer thermal energy.
Metals are good conductors. Some non-metals are good conductors, but many others are not.
The best conductors of electricity have that they are all metals in common.
Unlike metals, most nonmetals are gases at room temperature.

Metals are good conductors. Some non-metals are good conductors, but many others are not.
There are many great conductors in the world. These conductors include but are not limited to water and many metals.

Compounds (material's) that are good conductors are the ones that have many free electrons to cause electron drift. Free electrons are ones that are not closely bound to their nucleus and can move from one atom to another. copper, aluminium, silver are among the best. insulators such as plastic, rubber or any non metallic material do not have any free electrons, thus make good insulators. Resistors are materials as iron, nickel and nichrome. some of there energy is absorbed in the electron drift.
because they have many free electrons that can carry the electrical current
Metals have large number of free electrons, which are responsible for conduction of heat, electric current, etc. Hence metals are good conductors. Non-metal don't have such free electrons in them. Hence they are bad conductors. There are many such properties which differentiate metals from non-metals. for example, metals have a typical metallic luster ( except few), etc.
No, not always; There are many bad conductors which are reactive too.
Because of their many valence electrons. The free-moving electrons transmit heat quickly.
