Final answer:

A substance that reacts with metal but only dimly lights a conductivity tester is a non-metal.

Step-by-step explanation:

A substance that is able to react with metal but only dimly lights a conductivity tester is a non-metal. Non-metals are elements that are brittle when solid and do not conduct electricity or heat very well. They cannot be made into thin sheets or wires.
