He revived the atomic theory. He created Dalton’s law (gasses), Daltonism (colour blindness) and many other scientific discoveries. Dalton's atomic theory is : 1. All matter is made up of atoms2. Atoms are indivisible and indistructable 3. In 1897, as Cavendish Professor of Physics at Cambridge, Thomson discovered the electron which he had originally named as corpuscle.

8 Nov 2018 In 1897, J. J. Thomson discovered the first subatomic particle, the electron, while researching cathode rays. · To explain the neutrality of atoms,

s Dalton Eg 2 Thomson discovered that the negatively charged electron was part of the atom. It. Sep 4, 2009 Thomson took the idea of the atom and tried to incorporate the evidence for the electron. In this model, the electrons are the small things and Dalton and Thomson had a conversation about atomic theory? • Dalton: Atoms are indivisible.

JJ.Thomson discovered that atoms contain electrons which meant that atoms were not visible. His theory also stated that atoms were sphere like and had a positive charge. By: Colton and Emmanuel JJ. Thomson Atomic Theory His discovery Who is JJ. Thomson What his theory was

Cathode ray tube experiment A cathode ray is simply a glass tube where the majority of the air within the tube has been vacuumed out with electrodes at either side which was conducted by an electric charge that caused the tube glow.

Thomson's experiments with cathode ray tubes helped him to discover the electron (which Dalton did not know about). Dalton thought that atoms were indivisible particles, and Thomson's discovery of the electron proved the existence of subatomic particles. This ushered in a model of atomic structure referred to as the plum pudding model.
