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.
An atomic model of Dalton doesn't exist; the model of Thomson was called plum pudding model.
John Dalton stated "all atoms of a given element are identical"; discovery of isotopes by Thomson infirmed this old hypothesis.
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.
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.
Since the atomic mass consists of protons and neutrons, adding a proton would add one unit to the atomic massguessing that the number of neutrons doesn't change.
thomas discovered that the atom contained smaller particals called electrons
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.

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.

Variables that do not change in an experiment are independent variables.
Variables that do not change in an experiment are independent variables.
There are different types of factors that can change in an experiment. The environmental factors may change, and are out of your control. The variables in the experiment may also be changed but, are usually controlled by the individual conducting the experiment the majority of the time.
