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.
The beam bending towards the positively charged plate indicates that the cathode rays are negatively charged. This observation led Thomson to conclude that the cathode rays are made up of negatively charged particles, which we now know as electrons.
J.J. Thomson is best known for his experiment with cathode rays, where he deduced the existence of negatively charged particles (electrons) in atoms. By measuring the deflection of these rays in a magnetic field, Thomson was able to determine the charge-to-mass ratio of the electron.
Thompson observed that these rays are negatively electrically charged.
J.J. Thomson discovered the electron in 1897. He conducted experiments with cathode rays that led him to propose the existence of these tiny, negatively charged particles. Thomson's discovery laid the foundation for our understanding of the structure of atoms.
The cathode ray experiment was discovered by British physicist J.J. Thomson in 1897. Through this experiment, he was able to demonstrate the existence of negatively charged particles (electrons) and their properties.
JJ Thomson.
The scientist who used a cathode ray tube to discover negatively charged subatomic particles was J.J. Thomson.
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.

They are found to be deflected by electric and magnetic field in the specific direction in which a negatively charged particle would get deflected.
Cathode rays are negatively-charged particles.
negatively charged
Thomson set out to prove that the cathode rays produced from the cathode were actually a stream of negatively charged particles called electrons.
Thompson observed that these rays are negatively electrically charged.
its negatively charged particles of matter,Thomson knew that opposites attract but these the positive charged anode,so he reasoned that the paticles must be negatively charged! : )! Wooooo! Go J.J Thomson
