Thompson's cathode ray experiment led to the discovery of the electron, which was a fundamental particle in the atom. This challenged the earlier model of the atom as a solid, indivisible sphere by proposing a structure of a positively charged sphere with negatively charged electrons embedded within it. Thompson's model contributed to the development of the modern atomic model.

How did Thompson experiment change Dalton and atomic model?
Thomson's experiment, particularly his cathode ray tube experiments, led to the discovery of the electron, which challenged Dalton's atomic model that considered atoms as indivisible particles. Thomson proposed the "plum pudding" model, suggesting that atoms are composed of a positive "soup" with negatively charged electrons embedded within it. This marked a significant shift from Dalton's idea of solid, indivisible atoms, introducing the concept of subatomic particles and paving the way for the more complex atomic models that followed.
How did Thomson's' experiment change Dalton's atomic model?
An atomic model of Dalton doesn't exist; the model of Thomson was called plum pudding model.
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.
What is the variable in an experiment?
The variable in an experiment is the element that is being tested or measured. It is the factor that can change or be manipulated to observe its effect on the outcome of the experiment. There are independent variables, which are manipulated by the researcher, and dependent variables, which are what is being measured.
Is a atomic change the same substance after it changes?
Yes, an atomic change involves rearranging the atoms of a substance to form a new substance. The new substance may have different properties than the original substance due to the change in atomic structure.

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.
