Describe conduction in metals as a free movement of electrons unimpeded by the lattice

  • The delocalised electrons in a metal lattice normally move in random directions, establishing a steady state with no net transport of electric charge.
  • When an electric field or potential difference is applied, it forces electrons in a common direction, with the average velocity of the electrons being proportional to the strength of the electric field.
  • The electron flow produced by a potential difference is superimposed on the random movement of electrons.
  • Metals are quite good conductors.
