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...

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...
