What is the difference between conductors, insulators, and metalloids? LOTSS OF POINTS!!!

A conductor is a material which contains movable electric charges, An insulator is a material that has a large band gap, or a large energy difference between the valence and conduction band, And a metalloid is a chemical element that exhibits some properties of metals and some of nonmetals.

Explanation:

The main difference between the conductor, semiconductor & insulator is in its conduction state. The conductors always conduct electric current while the insulators do no conduct. However, semiconductor conducts & blocks at different conditions.
