Thealuminum foil, steel wool, paper clip, copper, charcoal stick, and graphite pencil were good conductors and displayed metallic properties. The glass rod, plastic, rubber, and wood were poor conductors. Most of the samples with metallic properties contained metallic bonds. The exception was carbo...
