Any material that will readily release electrons is called:

• A. A conductor
• B. An insulator
• C. A semiconductor
• D. A dielectric

Answer: (A)

The main idea is electrical conductivity from free charge carriers. Materials that can move electrons easily under an electric field are conductors. Metals have loosely bound outer electrons that form a sea of charge carriers, so electrons can flow through the material when a voltage is applied. That ready tendency to let electrons move is what defines a conductor. Insulators hold onto their electrons tightly and resist flow, dielectrics are insulating materials used to store charge in devices like capacitors, and semiconductors conduct to a moderate degree under certain conditions. So a material that readily releases electrons is a conductor.
