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.
What else can I help you with?
Who invented the cathode ray tube in the 1970s?
William Crookes invented cathode ray tubes.The earliest version of the CRT was invented by the German physicist Ferdinand Braun in 1897.
What did the cathode ray tube tell us about atomic structure?
because Thomson saw the ray move from the cathode to the anode so the particles have negatively charge
What year were twinkies invented?
they were invented either in 1897 or in 1930.

Named the scientist who coined the term 'electron'?
The scientist who coined the term "electron" was J.J. Thomson. He discovered the electron in 1897 while working on experiments involving cathode rays.
What particle was found using a cathode ray tube?
British scientist Sir Joseph J. Thomson discovered in 1897 that cathode rays were made up of what are now known as electrons.
Which scientist did experiments involving a form of cathode ray tube?
It was the investigator J. J. Thomson who did experiments with an early cathode ray tube. You'll find a link below.
Which scientist is credited with discovering the electron?
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
What subatomic particle was first discovered?
This particle was the electron in 1897 (J.J. Thomson).
When did julius plucker discover the electron?
Julius Plucker did not discover the electron. The electron was discovered by J.J. Thomson in 1897 through his experiments with cathode ray tubes.
What late 1800's scientist found the electron and other smaller particles?
J.J. Thomson is the scientist who discovered the electron in the late 1800s through his experiments with cathode rays. He also proposed the plum pudding model of the atom, which suggested that electrons were embedded within a positively charged sphere.
What did the scientist Thomson discover?
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.
What particles did jj Thomson discover?
J.J. Thomson discovered the electron in 1897 while conducting experiments with cathode rays. This discovery was groundbreaking as it provided evidence for the existence of subatomic particles.
What did j.j Thomson experiment with?
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.
What did jj thomas discover?
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.
Who invented the negatively charged particle electron?
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.
