Electrons as particles

When we were discussing electric currents, and resistances, we viewed the electrons as tiny point particles with a certain mass and electric charge. Resistance was then said to arise from the collisions of electrons with other particles in a wire. This view of the electron as a particle is certainly correct in this situation; the electron here cannot be thought of as a wave.
