State whether the following statements are true or false: (a) Thomson proposed that the nucleus of an atom contains protons and neutrons. (b) The cathode rays obtained from all the gases consist of negetively charged particles called electrons. (c) The anode rays obtained from all the gases consist of positively charged particles called protons.
Is the positive terminal of a battery known as cathode and are anode rays positively charged?
All the gases form cathode rays and anode rays when electricity is passed through them: (i) What does the formation of cathode rays tell us about the atoms? (ii) What does the formation of anode rays tell us about the atoms?
