Answer:
A negatively ionized lithium paste is a conductor.
Step-by-step explanation:
A conductor is a material that conducts electricity. In other words, a conductor has little resistance to the movement of electric charge or electrons when an electric field is applied.
Insulating materials for electricity are those that offer a certain resistance to the movement of electrons or electric current. In other words, an electrical insulator is a material with a low capacity for conducting electricity.
The best conductors of electric current are metals due to the free electron clouds that favor the circulation of electric current through them.
So, a negatively ionized lithium paste is a conductor.
