Thomsons cathode-ray tube experiment demonstrated that
(a) The elm ratio of the cathode-ray particles changes when a different gas is placed in the discharge tube
(b) Cathode rays are streams of negatively charged ions
(c) All the mass of an atom is essentially in the nucleus
(d) The elm of electrons is much greater than the elm of protons
