I say pure metal because alloys are relatively poor conductors of heat and electricity. This is because alloys are formed by introducing foreign atoms into a metal. This leads to an increase in irregularities, which then obstruct the motion of a free electron. As the free electrons are unable...
Are metals conductors? Metals are anexcellent conductor of electricity and heatbecause the atoms in the metals form a matrix through which outer electrons can move freely. Are metals poor conductors? Conduction: Metals are good conductors because they have free electrons. Silver and copper are the...
