Question

which option lists materials in order by their ability to allow the flow of electrons, from least easily to most easily? a. semiconductor, insulator, conductor b. insulator, semiconductor, conductor c. conductor, semiconductor, insulator d. semiconductor, conductor, insulator

Explanation:

Insulators have very few free - electrons and resist the flow of electrons. Semiconductors have more free - electrons than insulators but fewer than conductors. Conductors have a large number of free - electrons and allow electrons to flow easily.

Answer:

B. Insulator, semiconductor, conductor
