![]() The neutrons and the protons are collectively termed as the nucleons. The nucleus has two particles named neutrons and protons. The atom also has electrons present near the nucleus, and the electrons are actually orbiting the nucleus. Atoms have a nucleus that is present at the center of the atom. ![]() The smallest constituent of the atom present in a substance or a matter is the electron. Other than finding the electrons, Thompson could also conclude that the mass-to-the charge ratio of the cathode rays was free of the properties of the gas or metal electrodes, which lead him to consider electrons as one of the basic constituents of all the atoms. These negatively charged particles were named as the electrons. As it is known that the opposite charges always attract each other while the like charges repel one another, Thompson was able to estimate that the particles involved here had some negative charge. These particles got emitted from the cathode with the negative charge and were repelled by an electric field’s negative terminal. Thomson was also able to estimate the mass-to-the charge ratio of the particles involved just by estimating the deflection extents of the rays of the cathode in the electric or magnetic fields having different strengths. This demonstration was capable enough to bring up the fact that the cathode rays have some charged particles. He showed that the cathode rays can be bent or deflected by the electric or magnetic fields present nearby. ![]() The deflection of the rays of the cathode was demonstrated by Thompson. J.J Thomson stated and proved that the most basic constituent of the matter was not atoms but atoms too had some constituents and those constituents could be some particles inside the atoms.
