The glass rod, plastic, rubber, and wood were poor conductors.Most of the samples with metallic properties contained metallic bonds. The exception was carbon.Carbon is a non-metal and therefore has covalent bonds. However, in this experiment, it exhibited metallic properties. Carbon in the form...
conductors, insulators, semi-conductor. Those substances which allow electricity to flow through it are known as conductors, which completely not allow electricity to pass through it is known as Insulators, and the one which is in the midway of the two is known as Semi-conductors....

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...
