A sample of mercury-conductor
A piece of glass-insulator
A rubber hose-insulator
A negatively ionized lithium paste-conductor
<u>Step-by-step explanation:</u>
Conductors are substances that allow the flow electricity through them whereas insulators do not permit the flow of electricity through them.
Mercury is a liquid metal and due to its metallic nature, it is a fair conductor of electricity because metals have free electrons that carry the electric charge through the material.
Rubber and glass are insulators whereas a negatively charged lithium paste is a conductor.
