By measuring the degree of deflection of the rays as they passed through these fields, Thomson could deduce several important properties of the particles in the rays, such as their charge and mass. His experiments revealed that the particles were deflected by the magnetic and electric fields in a manner consistent with particles that were much smaller than atoms and negatively charged.

The Plum Pudding Model, proposed by J. Thomson inwas his conceptual model of the atom, developed shortly after his discovery of the electron. In this model, Thomson envisioned the atom as a sphere of positive charge with negatively charged electrons embedded within it, much like raisins in a plum pudding a popular British dessert. This arrangement was hypothesized to balance the positive and negative charges, making the atom electrically neutral.

InJ. Thomson was awarded the Nobel Prize for his discovery of the electron and research on the conduction of electricity through gases. Thomson did not discover a new type of ray; he studied cathode rays, determining they were streams of negatively charged particles later named electrons. Thomson discovered that electricity conducted through gases in cathode ray tubes involves tiny negatively charged particles, which he identified as electrons.

Thomson conducted his experiments to investigate the nature of cathode rays and to understand the fundamental components of atoms. Thomson discovered the electron, a fundamental subatomic particle carrying a negative charge, pivotal to the development of atomic physics. Home J. J Thomson. Home Physics.

It proved the existence of isotopes. It led to the discovery of the nucleus. It identified the first subatomic particle. It confirmed the wave nature of particles. What prestigious award did J. Thomson receive for his discovery of the electron? Nobel Prize in Physics. Copley Medal. Franklin Medal. Royal Medal. Thomson determined that all matter is made up of tiny particles that are much smaller than atoms.

He originally called these particles 'corpuscles,' although they are now called electrons. This discovery upended the prevailing theory that the atom was the smallest fundamental unit. InThomson began studying positively charged ions, or positive rays. This led to one of his other famous discoveries in when he channeled a stream of ionized neon through a magnetic and an electric field and used deflection techniques to measure the charge to mass ratio.

In doing so, he discovered that neon was composed of two different kinds of atoms, and proved the existence of isotopes in a stable element. This was the first use of mass spectrometry.

Thomson married Rose Paget, one of his students, in They had one daughter, Joan, and one son, George Paget Thomson, who went on to become a physicist and win a Nobel Prize of his own. Thomson published 13 books and more than papers in his lifetime. He left research in to become Master of Trinity College. We strive for accuracy and fairness.
