Which option lists materials in order by their ability to allow the flow of
electrons, from least easily to most easily?
A. Insulator, semiconductor, conductor
B. Conductor, semiconductor, insulator
c. Semiconductor, insulator, conductor
O D. Semiconductor, conductor, insulator
The correct option that lists materials in order by their ability to allow the flow of electrons, from least easily to most easily, is Insulator, Semiconductor, and Conductor, which is in Option A.
What are an electron, an insulator, etc.?The ability of a material to conduct electricity depends on the number of free electrons that are available to move through the material. In an insulator, there are very few free electrons, which means that the material does not conduct electricity very well. Insulators are typically used to prevent the flow of electricity, for example, in electrical wiring, where plastic or rubber coatings are used to insulate the copper wires.
Hence, the correct option that lists materials in order by their ability to allow the flow of electrons, from least easily to most easily, is Insulator, Semiconductor, and Conductor, which is in Option A.
