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.
Thomson's discovery of the electron showed that atoms were not indivisible, as Dalton's atomic theory proposed. Instead, atoms were made up of smaller subatomic particles. This led to the modification of Dalton's atomic theory to incorporate the idea of subatomic particles within the atom.
Thomson'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.
Dalton 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 experiment showed that atoms contain subatomic particles, specifically electrons. This discovery led to the modification of Dalton's atomic model, which previously considered atoms to be indivisible and uniform. Thomson's model proposed the existence of electrons within the atom.
How did Thomsons experiment change Dalton's atomic model APEX?
Thomson's experiment showed that atoms contained smaller negatively charged particles called electrons, which was not accounted for in Dalton's atomic model. This led to the modification of Dalton's model to incorporate the presence of electrons within the atom. The discovery of electrons also laid the foundation for the development of the plum pudding model by Thomson, which described atoms as a positively charged sphere with embedded electrons.
If all four postulates of Daltons atomic theory are correct what would change about the boxes on the periodic table and Why?
If all four postulates of Dalton's atomic theory were correct, the boxes on the periodic table would not change. Dalton's theory helped establish the concept of elements as composed of atoms, leading to the organization of elements on the periodic table based on their atomic number and properties. The periodic table would still be structured according to the number of protons in the nucleus of each element's atom.
How did Ernest Rutherford change the atomic model based on his experimental results?
Ernest Rutherford's famous gold foil experiment led to the discovery of the atomic nucleus. This discovery changed the atomic model by replacing the plum pudding model with the planetary model, where electrons orbit a central nucleus. Rutherford proposed that the nucleus contained positively charged protons while the electrons orbited around it.
How did the discovery of radioactivity contradict Dalton's atomic theory?
The discovery of radioactivity contradicted Dalton's atomic theory by demonstrating that atoms could undergo spontaneous changes, such as emitting radiation. This challenged the idea that atoms were indivisible and unchangeable, as proposed by Dalton. Radioactivity also showed that atoms could break down into smaller particles, which was not accounted for in Dalton's theory.

How did Rutherfords findings change Thomsons plum pudding model?
Rutherford supposed that the atom had a central positive nucleus surrounded by negative electrons.
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.
