Thomson discovered that atoms can be cut. He found this out while studying rays traveling between charged metal plates in a vacuum tube. He discovered that the rays were consisted of negatively charged particles. He had just discovered electrons. He discovered all of this on a trip from America. Since electrons are so small, he believed that they could only be from inside of the atom. Since Thomson's discovery of the electron, John Dalton's theory that atoms are indivisible had to be changed.

∙ 9y agoThomson's discovery of the electron showed that there were things smaller than the atom that could be removed from the atom. Therefor the atom was not an "uncuttable" object as Dalton had proposed.

∙ 8y agoDalton didn't know about protons, neutrons, etc., so after Thomson discovered electrons, and then Rutherford discovered the nucleus and the presence of protons, the model of the atom changed dramatically.

How did thomsons experiment change daltons atomic model?
Thomson's experiments with cathode ray tubes helped him to discover the electron (which Dalton did not know about). Dalton thought that atoms were in.

How did the discovery of radioactivity contradict Dalton's atomic theory?
radioactivity proves that there are smaller particles in an atom that makes it up, they are proton, neutron, and electron. Dalton's atomic theory clearly states that the atom is the simplest particle. Radioactivity contradicts Dalton's theory since it proves that there are particles which are simpler than the atom.
Does the atomic number changes when an ion is formed?
No, the atomic number does not change when an ion is formed. The number of protons does not change when an ion is formed, so the atomic mass would not change.

How did Thomson experiment change Dalton atomic model?
John Dalton stated "all atoms of a given element are identical"; discovery of isotopes by Thomson infirmed this old hypothesis.
