Detailed explanation-1: -A cathode ray tube consists of a stream of protons. In a neutral atom, the number of protons is equal to the number of neutrons. Gamma decay emits energy, but no particles. An alpha particle is the equivalent of a Helium-4 nucleus.
Detailed explanation-2: -(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.
Detailed explanation-3: -Cathode rays are streams of electrons observed in vacuum tubes (also called an electron beam or an e-beam). If an evacuated glass tube is fitted with two electrodes and a voltage is applied, it is observed that the glass opposite the negative electrode glows from the electrons emitted from the cathode.
Detailed explanation-4: -Cathode rays consist of negatively charged particles. When cathode rays are subjected to an electrical field, these get deflected towards the positively charge plate i.e. Anode.
