Electrons are in atoms found even in the human body.
J.J. Thomson used the cathode ray. Thomson's cathode ray experiment was when he shot a narrow beam of electrons through a cylindrical tube and deflected the electrons off of electric and magnetic fields, thus measuring the effects that those fields had on the direction of the beam.
electrons A: It is basically a glass vacuum enclosure whereby electrons are emitted from a cathode by a heating element. A grid control the flow of these electrons and finally hit the face of the tube where is rare earth materials emit photons

J.J. Thomson used cathode ray tubes to prove the existence of electrons.
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.
Yes they are the same. A cathode ray tube (CRT) uses an electron gun to "shoot" electrons from the cathode to specific positions on the anode of the CRT.
The cathode of an electron gun.
JJ Thomson discovered electrons using a cathode ray tube.
J.J Thompson discovered the electron. He also performed the Cathode Ray Tube Experiment and that told him that electrons are negative J.J Thompson discovered the electron. He also performed the Cathode Ray Tube Experiment and that told him that electrons are negative
The electron had already been discovered. It took little imagination to "see" that the cathode ray was the beam of electrons that originated from the cathode. And the beam was controlled using techniques based directly on what was correctly understood about the electron. The cathode ray could only be an electron beam generated at the cathode. Conventional elctric current flow is usually thought of as flowing from positive to negative, but at the quantum level; due to electrons having a negative charge; technically they really flow from negative to positive, and this is apparent in the cathode ray tube. Its the negatively charged electrons that glow in a cathode ray tube, and do so from the negative terminal, or cathode, hence the name.
J.J.Thomas discovered that atoms have negatively charged particles called electrons. He discovered this using the Cathode Ray. The cathode ray is a beam of electrons emitted by the cathode of an electrical discharged tube.
Because an electron carries a negative charge and in electricity, opposites attract. Particles with a negative charge will be drawn to the positive charge in the cathode tube.
British scientist Sir Joseph J. Thomson discovered in 1897 that cathode rays were made up of what are now known as electrons.
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.
J.J. Thomson used the cathode ray. Thomson's cathode ray experiment was when he shot a narrow beam of electrons through a cylindrical tube and deflected the electrons off of electric and magnetic fields, thus measuring the effects that those fields had on the direction of the beam.
This beam of electrons is emited by the cathode under voltage difference.
