They found that the rays bent towards positively charged plates and away from negatively charged plates. Knowing that objects which have like charges repel eachother, they concluded that the rays have a negative charge.
The negatively charged particle electron was discovered by J.J. Thomson in 1897 through his experiments with cathode rays. Thomson's experiments led him to propose the existence of the electron as a fundamental subatomic particle.
J. J. Thomson discovered the electron using an experiment involving cathode rays and a magnetic field. When subjected to the magnetic field, the cathode ray was deflected. If the magnetic field was flipped, the cathode ray was deflected in the opposite direction. This proved that a cathode ray was a stream of negatively charged particles that would later be deemed electrons.
J.J. Thomson's cathode ray experiment suggested the existence of negatively charged particles, later known as electrons. By studying the behavior of cathode rays in a vacuum tube, Thomson determined that these particles were much smaller than atoms and had a negative charge. This discovery led to the development of the plum pudding model of the atom.
Thompson's cathode ray experiment led to the discovery of the electron, which was a fundamental particle in the atom. This challenged the earlier model of the atom as a solid, indivisible sphere by proposing a structure of a positively charged sphere with negatively charged electrons embedded within it. Thompson's model contributed to the development of the modern atomic model.
Ernest Rutherford, a New Zealand physicist, designed an experiment that led to the first successful detection of an individual subatomic particle, the proton. This experiment, known as the gold foil experiment, involved bombarding gold foil with alpha particles to study the structure of the atom.
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.
The negatively charged particle called electron.
Thomson's experiment with cathode rays proved the existence of negatively charged particles, which he called electrons. This discovery laid the foundation for the development of the modern atomic theory and revolutionized our understanding of the structure of the atom.

Electrons--the cathode is negatively charged, the anode is positively charged.
He hit plates with light

J.J. Thomson used cathode ray tubes to prove the existence of electrons.
The charge of the particle in cathode rays is negative. This was determined by J.J. Thomson through his experiments with cathode ray tubes in the late 19th century, which led to the discovery of the electron.
