Thomson conducted the experiment.
The cathode ray tube experiment provided the first evidence for subatomic particles or, more specifically, electrons.
For a more in-depth explanation: when Thomson conducted this experiment, he set up the cathode ray tube, which sent a beam across the tube (which we know now is made of electrons, but at the time no one knew what an electron was or how they related to electricity). He then brought a magnet near the tube and found that it repelled the beam in the opposite direction, in the same way that a wire carrying a current was deflected by a magnet.Therefore, he concluded that whatever particle was part of the beam, it must be negatively charged.
Moreover, Thomson did this experiment with different metals at the cathode. We know that any metal is going to emit electrons to create the ray, but again, back then they didn't know what electrons were. No one had yet managed to disprove the theory that atoms were indivisible. But by using the different metals and getting the same results, Thomson's theory suggested that all atoms had the exact same negatively charged particles inside them, which is exactly what we know today.

In a directly heated cathode, the filament is the cathode and emits the electrons. In an indirectly heated cathode, the filament or heater heats a separate metal cathode electrode which emits the electrons.

In a cathode ray tube (CRT), the particles, which are electrons, originate at the heated cathode, becoming the so-called cathode rays. The electrons stream off the cathode and rush over to the anode.
1 answer
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.

Cathode rays are negatively charged because they are composed of electrons, which have a negative charge. When a high voltage is applied to the cathode in a vacuum tube, electrons are emitted from the cathode and accelerated towards the anode, creating a beam of negatively charged particles known as cathode rays.

The negatively charged electrode of a cathode ray tube (CRT) is the cathode. The tube is a cathode ray tube, and electrons stream off the cathode, are accelerated across the evacuated space and "directed" either electromagnetically or electrostatically, and then strike the phosphor coating on the positively charged anode at a "location" determined by the "directing" elements.

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.

The cathode is the positive terminal in a battery.

There is no such thing as anode rays. The cathode rays (aka electron beam) just travels from cathode to anode.
1 answer
The element forming at the cathode will depend on what elements are present. Reduction takes place at the cathode, so whatever element is being reduced, that is the one that will be produced at the cathode.
1 answer
Cathode rays are streams of electrons that travel from the negatively charged cathode to the positively charged anode in a cathode ray tube. They are not material particles in the traditional sense because they do not have mass or volume, but rather behave as electron beams.

Cathode rays are negatively charged particles that move in curved paths in the presence of a magnetic field. The direction and curvature of the cathode rays can be controlled by adjusting the strength and orientation of the magnetic field. This phenomenon is known as the magnetic deflection of cathode rays and is used in devices like cathode ray tubes.

No, the cathode is typically negative in an electrical circuit.
1 answer
Reduction occurs at the cathode in an electrolytic cell. This is where cations in the electrolyte solution gain electrons and get reduced, leading to the deposition of a substance onto the cathode.
