Why did Thomson choose electric current only and also electrons were already discovered during the flow of electricity.why didn't Thomson choose any other rays or any thing to conduct the canal ray experiment.
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.
According to Thomson, positive charges were 183 times greater than electrons in magnitude; hence the atom as a whole was positively charged.
Anode rays were discovered by
