Thomson observed cathode rays with every element because cathode rays are composed of electrons, which are fundamental particles present in all atoms regardless of the element. When a high voltage is applied in a vacuum tube, electrons are emitted from the cathode and accelerate toward the anode, creating cathode rays. This universal presence of electrons in all elements allowed Thomson to consistently detect cathode rays across different materials. His experiments demonstrated that these rays were not dependent on the type of gas or metal used in the cathode.
Thomson observed cathode rays regardless of the element tested because cathode rays are composed of electrons, which are fundamental particles present in all atoms. When a voltage is applied in a vacuum tube, electrons are emitted from the cathode and travel toward the anode, creating the rays. This universality in the presence of electrons explains why he consistently saw cathode rays across different elements. Thus, the experiment demonstrated that electrons are a common component of all matter.
The deflection of cathodic rays was the source of inspiration for Thomson.
Thomson was experimenting with currents of electricity inside empty glass tubes.
J.J. Thomson discovered that cathode rays are made up of negatively charged particles. He conducted experiments using cathode ray tubes and found that the rays were deflected by electric and magnetic fields in a manner consistent with the presence of negatively charged particles.
J.J. Thomson used a cathode ray tube to discover electrons. By passing an electric current through the tube, he observed the deflection of a beam of electrons, which led to his conclusion about the existence of electrons.

No. JJ Thomson's experiments with cathode rays lead to the discovery of the electron.
After experiments with cathode rays Thomson discovered that these rays are deflected in an electrical field; and from this he proposed the existence of electrons.
Cathode rays were discovered by JJ Thomson and carry a negative charge Anode rays were discovered by Goldstein and carry a positive charge.
J.J. Thomson studied the deflection of cathode rays in electric and magnetic fields.
J.J. Thomson experimented with cathode rays in a vacuum tube, which led to the discovery of the electron in 1897. By measuring the charge-to-mass ratio of electrons, he determined that they were a fundamental particle and were present in all atoms.
The immaterial nature and the aetherial hypothesis of cathode rays were proved wrong by J. J. Thomson. He concluded that the rays were comprised of particles. His entire works can be divided into three different experiments. In the first, the magnetic effect on cathode rays was studied while in the second, the rays were deflected by an electric field.
Cathode Rays
J. J. Thomson experimented with cathode rays and discovered the electron, leading to the development of the plum pudding model of the atom.
Thomson hadn't an instrument; this model is only a hypothesis.
J.J. Thomson is credited with discovering the electron through his experiments with cathode rays in 1897. He observed that cathode rays were negatively charged particles and proposed that they were a fundamental component of all matter.
Thomson observed that cathode rays were deflected by electric and magnetic fields in a manner consistent with them having a negative charge. He measured the charge-to-mass ratio of cathode rays and found it to be the same regardless of the material used for the electrodes, which suggested the charge was a fundamental property of the particles themselves.
