Is metals a good conductor

WitrynaMetals are good conductors (both of heat and electricity) because at 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. In good insulators, such as glass, all of the electrons are tightly bound to atoms (which are fixed), and so there are no free electrons.
