why are anode rays called positive rays?

A : The charge to mass ratio of the particles anode rays depends on nature of gas taken the discharge tube . R : The particles of anode rays carry positive charge

Canal rays are positively charged.

All the gases form cathode rays and anode rays when electricity is passed through them : (i) What does the formation of cathode rats tell us about the atoms ? (ii) What des the formation of anode rays tell us about the atoms ?

Name the gas which produces anode rays consisting of protons in the discharge tube experiment.
