When a high voltage is applied across the metallic electrodes of a discharge tube filled with a gas under reduced pressure, the molecules of the gas are dissociated into atoms. Now when high speed electrons (i.e. cathode rays), originated from cathode strikes these atoms, the atoms are converted into cations which pass through the holes of the cathode and constitute positive rays. The electrons obtained in the conversion of the gaseous atoms into cations move towards anode as negative rays.
M + e-(originated from cathoode) => M+ + 2e-
Gaseous Atoms Pass through the perforated Move towards anode
cathode as positive rays as negative rays
Now it is believed that the protons like electrons are also the common universal constituents of all atoms, excepting hydrogen which has no neutron.
