Almost all good conductors of electricity known to man are metals or alloys. The problem of using exposed metal as conductors in electronics is that they tend to oxidize rather rapidly. Oxidized metals then go on to become poor conductors of electricity. On...
Why are metals good conductors of heat and electricity? Metals are good conductors (both of heat and electricity) becauseat least one electron per atom is free: i.e., it is not tied to any particular atom, but is, instead, able to move freely throughout the metal. ...
Is iron a metal, nonmetal or metalloid? What charge do nonmetals have? What elements are the poorest conductors of electricity? Which are more common: metals or nonmetals? Do nonmetals have high or low boiling points? Do nonmetals gain or lose electrons?

What are non-ohmic conductors? Differentiate between conductors and insulators. Insulators also contain electrons, but they are not conductors, Why? What makes something a conductor, insulator, and semiconductor? What property makes metal a good conductor and rubber a good insulator?
although they lack the classification of a proper metal. While at room temperature, metalloids have poor conductivity. However, when heated, they become relatively good conductors. Adding metals to their structure helps in this regard. Boron, silicon and germanium sit in this designation, and they...
