- Empty MOs that are higher in energy constitute the conduction band.
- In metals, the valence and conduction bands overlap, so electrons can move from the valence band to the empty conduction band
- Thus, electrons are completely delocalized, free to move throughout the piece of metal, explaining why metals conduct electricity well.
- Metals conduct a current well (conductors), whereas most nonmetals do not (insulators).
- The conductivity of metalloids lies somewhere in between (semiconductors).
