Is it correct that if a substance does not hold one of its electrons tightly, then it will conduct electricity because flowing electrons create electrical current?
Question Date: 2015-04-16
Answer 1:

Yes, you have given a nice, concise definition of electrical conductivity. This applies to metals, which are described as having a “sea” of electrons that move and flow easily around the positively charged atom cores. It also applies to semiconductors, which are so called because they have some closely bound electrons in the “valence band” and some loosely bound electrons in the “conduction band.” The conduction band electrons are the ones that contribute to the overall conductivity of the material. Semiconductors include materials like silicon, which is used in computer chips and solar cells.

Answer 2:

Yes,it is correct. That is why metals are good conductors of electricity.
