itIt is common knowledge that electrons are mobile and therefore used in conductivity. electronsElectrons move freely within the structure of an atom but protons are bound in the nucleus and therefore immobile. conductivityConductivity will therefore occur wenwhen electrons move from one atom to another and not protons due to their immobility. weWe now learn particles are involved in conductivity and this particles will only aid in conductivity if they move.
