What evidence convinced Thomson that cathode rays consist of negatively charged particles?
In a series of experiments in the 1890's, J.J.Thompson showed that cathode rays, or electrons, are deflected by an electric field, they are bent by a magnetic field, and that their charge to mass ratio is about 1/2000th of that of the proton. Light does not have any of these properties.

What evidence did J.J Thomson provided about this structure of an atom?
J.J. Thomson provided evidence about the structure of an atom through his discovery of the electron using cathode ray tubes. His experiments showed that electrons are negatively charged particles and are present in all atoms, leading to the development of the plum pudding model of the atom.
What experiment do Thomson do?
He hit plates with light
How did J.J. Thomson discover negative charges?
J.J. Thomson discovered negative charges by studying cathode rays in a vacuum tube, where he observed that they were deflected by electric and magnetic fields in a way consistent with negatively charged particles. This led him to propose the existence of negatively charged particles, which he later named electrons.
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.
How did Thomson know that the glow in the CTR was from a stream of charged particles?
Thomson knew that the glow in the cathode ray tube (CRT) was from a stream of charged particles because the particles were deflected by electric and magnetic fields, indicating they were negatively charged. By measuring the deflection of the particles, he was able to calculate the charge-to-mass ratio of the particles, leading to the discovery of the electron.
What did Thomsons experiments prove?
Thomson's experiments with cathode rays proved the existence of negatively charged particles, which he called electrons. This discovery provided evidence for the existence of subatomic particles and laid the foundation for the development of the modern atomic theory.
Who discovered small negatively charged particles inside an atom?
J.J Thomson
What evidence did Thomson have that his glowing beam contained negative particles?
J.J. Thomson discovered that his glowing beam contained negative particles by observing the deflection of the beam in an electric field and measuring the charge-to-mass ratio of the particles. This led to his conclusion that the particles in the beam were negatively charged electrons.
What evidence did J.J Thomson provided about this structure of an atom?
J.J. Thomson provided evidence about the structure of an atom through his discovery of the electron using cathode ray tubes. His experiments showed that electrons are negatively charged particles and are present in all atoms, leading to the development of the plum pudding model of the atom.
What evidence convinced J.J Thomson that an atom consist of more than electrons?
The evidence for JJ Thomson was that the plum pudding model could not predict why atoms absorbed and emitted spectral lines.
What experiment do Thomson do?
He hit plates with light
Who Discovered that atoms contain negatively charged particles called electrons?
In 1897, a British scientis named J.J. Thomson.
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.
Which scientist used a cathode ray tube to discover negatively charged subatomic particles?
The scientist who used a cathode ray tube to discover negatively charged subatomic particles was J.J. Thomson.
Which scientist discovered that cathode rays are made up of negatively charged particles?
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.
How did Thomson's experiment change Dalton's atomic model?
Thomson's experiment provided evidence for the existence of electrons within atoms, leading to the modification of Dalton's model to include subatomic particles. Instead of envisioning atoms as indivisible spheres, Thomson's discovery suggested that atoms were composed of smaller, negatively charged particles (electrons) embedded within a positively charged sphere.
What Thomson called corpuscles are now called what?
What Thomson called corpuscles are now referred to as electrons.
