Question
All the gases from cathode rays and anode rays when electricity is passed through them :What does the formation of cathode rays tell us about the atoms?

Solution
A cathode ray is a stream of high velocity electrons that are produced in a vacuum tube between a negatively charged cathode and a positively charged anode. Formation of cathode rays tells about the presence of electrons in all the atoms.
